The manga provides the following examples:
Absence Makes the Heart Go Yonder: Somewhat. The long distance strains Ann and Daigo's relationship as they find it harder to communicate and it allows others such as Fuji and Shika to fall in love with them and attempt to take them for themselves. However neither hugely impacts their relationship. It's their insecurities and Ann's concern for Daigo's happiness that breaks them up.
Annoying Younger Sibling: Mostly averted with Chii, who is Ann's younger step-sister. There's tiny signs of brattiness that's typical of any young sibling, otherwise she's mostly a good-natured kid who's concerned for her sister's wellbeing.
Played straight with Shika to Fuji, who doesn't really treat her that kindly and isn't close to her.
The first bonus chapter in volume 10 shows a flashback of a young Daigo thinking his newborn sister will be this and would rather be an only child. He has a change of heart after finally meeting her though. In the present day, his sister seems to avert this as she doesn't really get in his way and even makes a good-luck charm for him during exams, which he does bring while he takes them.
Beach Episode: Ann, Fuji and their friends go on a trip there during their school break in Tokyo.
Broken Bird: Ann, whose mother's suicide causes her to become emotionally unstables at times. This haunts her right to the end, where she gets a You Are Not Alone speech from her grandma after suffering a near-fatal wound from glass.
Ann's grandmother briefly becomes this after her daughter's suicide, blaming herself for telling her to get a hold of herself instead of to do her best. Ann snaps her out of it, saying it was her mum's fault for being weak.
Also Shika, after she finds out she is the illegitimate child of the family, not Fuji.
Chick Magnet: Despite his questionable personality, many girls in both Shimane and Tokyo adore Fuji for his good looks and cool aura.
Early-Bird Cameo: The little girl at the very beginning is Chii, Ann's younger step-sister. Chances are the reader has forgotten about her by the time she's introduced.
Disappeared Dad: Ann's father, who divorced Ann's mother because out his debts. He returns early into the story to take Ann back with him to Tokyo.
Fuji's and Shika's mother had an affair a number of years ago, and the rumors go that the man is Fuji's biological father, who is revealed to be a sleaze bag and wants nothing to do with Fuji, leaving him sickened that he is related to such a man. It is only later revealed to be Shika's biological father and not Fuji's.
Hopeless Suitor: Fuji for Ann. Even when they become a couple, Fuji soon realizes that Ann will always love Daigo.
Ayumu and Shika for Daigo.
How We Got Here: The manga begins with a young girl bugging her older sister who's about to move to America with her fiance and they find the latter's hourglass. That older girl, Ann, then thinks back to how she got that hourglass and its significance to her.
Jerk Ass: Sakura, the older man Ann befriends at age 26 and whom she's briefly engaged to. He has a hatred for feminine women who are weak and cry a lot, and is a little manipulative. Ann eventually calls him out for this attitude towards his ex, which leads him to angrily break off the engagement. He becomes a tiny bit better after encountering Chii and Shika in America.
Shotgun Wedding: Somewhat with Ann's dad and Kaede. After finding out she's pregnant, the latter first wants to break off their relationship so the former doesn't have to worry about them, but Ann convinces her he loves her enough to not leave her side, and so they decide to marry before the child is born.
Victorious Childhood Friend: Ann and Daigo are zig-zagged with this. They become a couple, then have a falling out but then reconcile... only to break up afterward. After many years apart, they finally get back together.
Wicked Stepmother: Averted with Kaede, who eventually marries Ann's father and is one of Ann's role models. It's even Ann who has to convince her that her dad does love her and that they should stay together.
