Sukisho (also sometimes spelled Sukisyo, its formal title being Suki na Mono wa Suki Dakara Shôganai!! or "I like what I like, so there!") is a Boys LoveLight Novel on which a 12-episode anime series and Boys Love Game are based.The story of Sukisho focuses on high school students Hashiba Sora, who lost his entire memory when he fell out of a 4th story window, and Fujimori Sunao, who just transferred to the same school after having disappeared for years. After being released from the hospital, Sora meets Ran, Sunao's second personality. Though Ran seems to despise Sora, he claims that Sora also shares his body with a second person, Yoru, who happens to be Ran's boyfriend. Unfortunately, Yoru and Ran tend to come out mostly when Sora and Sunao are asleep and tend to make the most of the limited time they have together. Hilarity and insanity ensue.Though Sukisho has a definite BL theme, it also has many aspects of a mystery show, solving the secret of Sora and Sunao's Dark and Troubled Past. As the show continues, more evidence is uncovered that Sora's fall was no accident, Yoru and Ran are not what they seem to be, as well as some darker themes from when they were childhood friends. And then there's another party hiding in the shadows...The anime is a highly severe case of Cast Full of Pretty Boys, with no female characters appearing on screen at all. The closest thing is Wholesome Crossdresser Nanami, who is feminine to an extreme, and seems Happily Married with Shinichirou.Note that while the anime is light and fluffy - the game is much, muchdarker, rated M, and may require a tissue.The games are slowly being translated piecemeal here.Due to the differences and increase in tropes, we’ve split the anime and games into two.
The series as a whole provides examples of:
Adaptation Dye-Job: Sunao actually has “brick colored hair” in the games. Ran is originally the only one who has pink.
Affectionate Nickname: As children, Sora referred to Sunao as "Nao" and Sunao referred to Sora as "Kuu-chan" and they call each other this on occasion. Matsuri addresses Sunao as "Nao-kun" and Shinichiro is called "Onii-chan" by Sora and Sunao.
All There in the Manual: Numerous artbooks, game guides, novels, audio dramas, and manga have been released for the series. One guide even goes as far as to detail the characters' daily schedules and school report cards.
Beam Me Up, Scotty!: The anime has Phantom 416 telling Sora that he's going to take something important away, while in the game it's Chris who says this. Both are referring to someone different.
Though most probably not legally married, Shinichirou and Nanami qualify for this trope. They have wedding bands and are pictured in the Sukisho artbook driving in a 'Just Married' car; Shinichirou in tux and Nanami in bridal gown.
Adaptation Personality Change: Hiromu. In the anime, he's a wandering spirit and a Crazy JealousBratty Half-Pint who was threatening to kill Sunao for getting in the way of him and Sora, though he turns out to be more a Shrinking Violet when he shows up in school. In the game, his spirit temporarily inhabits Sunao's body and is much more understanding towards Sunao, at one point deciding to not use Sunao's body to have sex with Sora when he realizes how much it bothered Sunao. Furthermore, he later becomes a Shipper on Deck for Sora and Sunao.
Disproportionate Retribution: Sunao's revenge seems quite over the top, making plans of outright murder, just because his childhood friend let go of his hand in a life-or-death situation. However, in the games the revenge doesn't seem so drastic, because Sora instead killed both of their parents.
Dragged into Drag: Sunao in episode 2, according to Sora, the outfit he wore really suited him.
Love Epiphany: Sora realizes he loves Sunao after hearing their back-story in the lab and the two have sex and Sunao seems to have one as well when he and Sora have sex, but turns out it's quite the opposite but has his second and real one when Sora comes to rescue him.
Luminescent Blush: Both Sora and Sunao blush pretty badly when there's an implication of romance between the two of them, but Sunao does it more often; the two most memorable times being in episode 4 when he thought Sora was going to say Sunao was his most greatest treasure and the second being in episode 7 when Sunao watches Sora take off his shirt.
Sora gives the most intense blush in the OVA when the kids teased the two when they saw Sunao eat a grain of rice off of Sora's face.
Nice Job Breaking It, Hero: Sunao tries to save Sora (who’s terrified of fire) from Aizawa holding a lighter to his face. He then tackles him, which ends up setting the whole place on fire.
Official Couple: Nanami and Shinichiro are a couple from the start of the anime, Sora and Sunao have sex in episode 10 and become official by the end of the series, and Kai and Gaku are seen official during the OVA.
Critical Annoyance: Every time Sora remembers something painful (or if Yoru is acting up enough) the most earsplitting sound effects would start to play. This was especially annoying because you were reading quietly during these scenes until it suddenly started blaring, and to unlock all of the endings (per game) you had to go through them over and over again.
Defiled Forever: Ran is noticeably depressed for what Aizawa did to him, to the point that while he has sex with Yoru, he’s apologizing and crying over and over again for being “dirty.” This also makes him a bit of Stepford Smiler considering his personality.
Did They or Didn't They?: There are some days that end with Ran and Yoru talking and then abruptly ending, and by morning the player isn’t sure if anything happened or not. Becomes hilarious when a clearly pissed Sunao wakes up in bed with Sora, and you know they did.
Downer Ending: The canon ending of the third game ends with Sunao and Shinichirou, who had been stabbed by Sora and Sunao, being taken away by Aizawa as Shinichirou and Nanami's apartment is completely destroyed.
There’s another one in the fourth, where Sora believes that Sunao is so far gone that he stabs him, and it’s implied that he also stabs himself. They then “fall asleep” holding each other in a bed of blood. And flowers.
Generation Xerox: Sei, Shiina, and Kitamura. Sei is literally a clone of Sora, Shiina looks like Nanami but is the Sunao of the group, and Kitamura, while not related to Matsuri, is the one who gets them into trouble.
Sora gets his fair share by virtue of being the main character. Canonically Sunao, Hiromu, and Minato are in love with him.
While Nanami and Shinichirou are an item, they're not immune to this either. Aizawa wants Shinichirou for himself, and Chris also has a crush on Nanami, while Shinichirou's quasi-Split Personality Minato has an unusual fondness for Sora.
The Reveal: The first is when Sora realizes the boy he's been dreaming of leaving behind in a dark tunnel was actually a memory of Sunao, but the biggest one happens in Rain, where Sora learns he killed both of his and Sunao’s parents under Aizawa’s Mind Rape, all in front of Sunao’s eyes.
