Voiced by: Mitsuo Iwata (radio drama) and Yuji Ueda (OVA)
Portrayed by: Sō Yamanaka (TV series), Shinnosuke Fukushima (web series), Riki Miura (1st film) and Hikaru Okada (2nd film)
The series' protagonist, a 25-year-old elite salaryman for a foreign cosmetics maker.
- Accidental Pervert: Don't know how "accidental" as Makoto gets throughout the series.
- Big Brother Mentor: Give advice to his Male co-workers expect for his Male friends.
- Catchphrase: A "Here I go!" or something similar whenever he is about to, ahh, engage Yura.
- Chick Magnet: Pretty much the entire female cast has shown at least fleeting interest in him, with some having outright obsessions. Especially weird given that the fact he is married.
- Clueless Chick-Magnet: Has no idea that he's the object of multiple women's affections, even in cases where it's blatantly obvious.
- Genius Ditz: He's actually quite competent at his job and is something of a rising star in the office. When it comes to everyday affairs, particularly romantic ones, he's completely clueless.
- Good Angel, Bad Angel: Had at least one visit from them.
- Happily Married: To Yura. Maintaining a stable marriage is the focus of the story.
- Idiot Hero: Far from the sharpest tool in the shed, almost always thinking about sex, and often fails to consider Yura's feelings. Still a good guy, though.
- Large Ham: Some of his reactions are over-the-top, especially when he has a hilarious mini-Heroic BSoD whenever Yura tells him she doesn't feel like having sex right now.Makoto: *in the depths of despair* You don't like me...Yura: What? That's not it...Makoto: You don't like my wieney...!
- Manchild: Despite being 25 at the beginning of the series he still clearly acts like he's still in high school.
- Nice Guy: He's thickheaded, but he tries his best to be a good husband and friend.
- Oblivious to Love: Despite being a Chick Magnet he never seems to pick up on the signals of a large number of females who have been crushing on him. In fact, he will never figure it out unless a woman directly propositions him.
- Old Maid: A rare male example at the very beginning. He's 25 years old, does quite well for himself at his job and is seen as attractive by most women, but he's still a virgin and terrified of remaining one. Luckily, he meets Yura not long after.
- Salaryman: One of Japan's typically overworked white-collar corporate drones, though at least he's risen to a decent pay grade.
- Speed Sex: Makoto's biggest issue is that, while he can "get ready" pretty quickly, more often than not he can't last a full minute without ejaculating, which leaves Yura unsatisfated. This continues past their first wedding anniversary.
- Thanks for the Mammary: Somehow always ends up groping someone's breasts by accident.
- This Loser Is You: To some degree Makoto is supposed to represent the uneducated male reader. The "narration" boxes have a particular tendency to make fun of his one-track mind and occasional bouts of Insane Troll Logic.

- Happily Married: To Makoto. The story focuses on maintaining one.

She eventually learns to embrace her sexuality more and cherishes how lovemaking lets her feel close to Makoto.
- This Loser Is You: Although she screws up much less than Motoko, the story assumes that female readers share her naivete about sex.

Makoto's mother, who takes great interest in her son's marriage and is hoping for grandchildren.
- I Want Grandkids: Whenever she gets in contact with Yura, she'll always drop the hit that there's still no babies in her marriage, and would blame Makoto's bed skill. She even asked Kyouko to get in the picture so she could make sure they have babies.
- Let Her Grow Up, Dear: While her husband was in shock about Jun's love life and was all about "Girls must remain maidens until marriage", she was more interested in how was her affairs and even points how she wasn't a virgin neither when she married him.

Akira Onoda
Portrayed by: Yuichi Tsuchiya (3rd film)
Makoto's big brother, a lawyer with a loud mouth who thinks it's his job to stick his nose in Makoto and Yura's business, and lecture them about lovemaking techniques with no regard for who's listening.

- Cool Big Sis: She's a better sex mentor to Yura than her husband is to his brother.
- Tsundere: She may love her husband but always has to hold him back everything he's admiring Yura's...and Rika's, and even Jun's beauty.
Jun Onoda
Makoto's little sister, who is innocent but curious about sex.
- First Guy Wins: After having some adventures mentioned below, finally makes an emotional connection with an e-mail pal. It turns out to be her first love, Inoue.
- Horrible Judge of Character: in her search for true love, she manages to
a) have a one-night-stand with a man she practically just met (who — shock! — turns out to have a girlfriend), right after breaking up with her boyfriend because she feels their relationship has lost the spark,
b) become the (oblivious) fifth sex-friend of an obvious playboy (despite the warnings of her best friend, she is devastated upon seeing him enter a love hotel with another girl) and
c) pursue an affair with a homely middle-aged married man, this time mere hours after first talking to him. One can almost not blame her father for calling for a family conference about her behavior... - Looking for Love in All the Wrong Places: Truly wants to find true love and a stable relationship, but because of her poor judgement she ends up sleeping with a bunch of different guys who turn out to be using her.
- Wide-Eyed Idealist: Has an incorrectly idealized idea of what sex and true love are supposed to feel like, and doesn't realize how many sleazy guys would trick a girl just to get into her pants.

- Big Ol' Eyebrows: Has unusually large eyebrows for a girl, which signify she's a Tomboy.
- But I Read a Book About It: She's a OB/gynecologist who knows about sex theory but as a virgin, has no practical knowledge.
- Old Maid: Kyoko is 30 years old and still maiden, which makes her anxious that she'll never lose her virginity or find a man. That is, until Matsuzaki came along.
- Tsundere: She's just as likely to Dope Slap Matsuzaki upside the head as she is to give him passionate doe-eyes.
Kawada Family
Hideki Kawada
Yura's father.
Chiharu Kawada
Yura's mother.
- Mum Looks Like a Sister: At 46 years old, she looks so young that she could pass of as her daughters' sister to strangers. This is because she got pregnant with Yura when she and Hideki were in college.
- Silk Hiding Steel: Chiharu is elegant and composed, but has a sharp tongue that can spit venom.
Rika Kawada
Yura's little sister, a college student and free spirit who is very promiscuous and knowledgeable about sex. This puts her in the funny position of teaching her clueless older sister about sexual matters. She has a boyfriend, Yamada, but frequently cheats on him with her various sex friends.

Makie Sugiyama
A flirty co-worker of Makoto who enjoys seducing married men.
- Insane Troll Logic: Comes up with some pretty flawed arguments to justify adultery.
- It Must Be Mine!: The reason why she only sleeps with married men is because she's the type of person that wants what other peoples have. That's her whole deal with wanting Makoto to cheat on Yura with her.
Manabu Okahama & Yosaku Inagaki
Those Two Guys at Makoto's office, who are clueless about the opposite sex and provide something of a foil to Happily Married Nice Guy Makoto. Manabu is the one with buckteeth and Yosaku is the sour face one.
- Casanova Wannabe: Okahama. Inagaki, meanwhile, has pretty much accepted that he'll never find a woman that's interested.
- Deadpan Snarker: Inagaki. Given his two best friend's personalities, it's understandable.

- Does Not Like Men: Turns out she's actually Makoto-sexual.
- Foil: Contrasts with the free-spirited and promiscuous Rika by being more prudish and straight-laced. Chapter 139 is dedicated to their opposite personalities.
- The First Cut Is the Deepest: The cause of her crush on Makoto.
- Mistaken for Gay: Since she has no interest in men and sex, a lesbian co-worker then assumes she's a lesbian as well. She tries to convence everybody that she's not gay with no results.

Kouichirou Matsuzaki
- Bishie Sparkle: He's accompanied by plenty of sparkles to further highlight his prettiness.
- The Casanova: Matsuzaki is definitely a player, though his antics usually don't work on several women in the story.
- Chivalrous Pervert: He's a serial womanizer, but he's a decent guy.
- Does Not Like Men: His goal in life is seducing women, so he finds men to be either annoyances or rivals. He comes around to Makoto later on, and even seems to warm up to Okahama and Inagaki as well.
- Henpecked Husband: When he starts dating Kyouko, he's forced to do everything she tells him to do while only responding with simple "Yes dear"s.

- Ladykiller in Love: His crush on Kyouko.
- Likes Older Women: Well, more like likes more experienced women.
- Sharp-Dressed Man: He's an impeccable dresser with a wardrobe consisting of crisp suits and polo shirts. Especially noticeable compared to the otherwise plainly dressed male cast.
- Stalker with a Crush: Has some vibes of this in his efforts to win over Kyouko. The fact that she exploits him as a chauffeur at first just makes their eventual hook-up that much creepier.
- Unknown Rival: To Makoto initially.
Arisa Miya
Miyuki's lesbian co-worker who is infatuated with her.
- Abhorrent Admirer: She's not ugly, but the object of her affections isn't a lesbian and wishes she would stop bugging her.
- Incompatible Orientation: She's infatuated with Miyuki, who is straight and only loves Makoto.

She ends up falling in love with Makoto, and finds herself unable to give up on him even after finding out he's married, but is too afraid to tell him her feelings.
- Boob-Based Gag.: Her breasts create a lot of physical comedy through Funbag Airbag and the usual slapstick gag.
- Buxom Beauty Standard: Her huge chest gets her a lot of male attention.
- D-Cup Distress: Her breasts are so huge that they seriously inconvenience her and the author uses her to illustrate every problem a woman with large breasts could possibly have, from sore shoulders, to difficulty finding bras or blouses that fit, to unwanted male attention, to people making assumptions about her personality.
- Single Woman Seeks Good Man: Is in love with Makoto because he is very nice to her.
- Shrinking Violet: She's quite shy and has a hard time speaking up for herself.
