Yorokobi wa Ude no Naka
Uke is in love with his younger brother. Because of this he moves out of his home and lives with seme (41 years old). Seme likes uke for a really long time ("13 years of affection"! - p.76) and it's his first love too! (p.83)
Ai no Poltergeist
Ch.1: student (pretends to be a M) x student (everyone thinks he's a S, in fact he's a M) Ch.2: ghost x human (human's first love is the ghost) Ch.3: student x student Ch.4: seme likes cats and is a M while uke is a S Ch.5: student x student (uke punches seme) Ch.6: uke spoiled the guys he dated until they turned useless Ch.7: detective (seme) x forensic investigator (uke, but he usually was seme) Ch.8: about twins
Hina wa Mitsuiro no Koi ni Torawareru
At first seme (boss) only played with uke (subordinate): he made him fall in love with him und then dumped him (uke (me too^^) thought seme loved him too). Uke ended their "relationship", avoided seme and changed workplaces. Later seme missed uke and he felt worse until he realized that he loved uke. Seme tried to apologize and confess his feelings but uke ignored him. Seme's health got worse because of the whole situation until he collapsed at work. In the end uke still loved him and both are now once more all lovey-dovey. - uke was in love with his best friend who married - uke is seme's first love
