Angel Demon's Questions (2)

Read this Yaoi School Life manga back in 2010 and the manga has inter-linked-stories/collections-of-stories. The first (main) story is about a high-school sensei (school-doctor/teacher) and a high-school student couple. The second story which follows is at the same high-school and is a student and student relationship with a tough looking high-school delinquent seme with medium length light hair who wears a loose-open-school-uniform-shirt over a t-shirt (he is friends with the boy from the first story) and he is taller than the short timid high-school uke with dark hair who wears his school-uniform neat-and-proper. They kept meeting up in the school-rooftop and they soon began to sleep together. There is a time-skip/time-jump that happens during the second storyline where this couple are arriving at their college entry and both the seme and uke appear to be older-young-men now. Only the uke is much taller and muscular than the slender seme. The muscular/tall uke is still timid even though he is getting noticed by college-girls like he is eye-candy to these girls which the uke does not realize how good-looking he is from his growth-spurt. One day during sex (in their dorm-room/bedroom/apartment), the muscular/tall uke confesses that he hates still being a virgin, more so now that he is muscular/taller than the seme, and he wants to have sex like real men do. The seme starts planning to get a college-girl to sleep with his boyfriend so the uke could lose his virginity. The seme is going to talk to his college-female-friend who likes uke (his lover), but she does not know that they are boyfriends. The seme loses his nerve in asking her because he doesn't have confidence that he can keep his boyfriend after the uke sleeps with a college-girl. In the end, the seme decides to bottom for the uke (that way nobody but him touches his lover while he makes his boyfriend a man). If anybody knows this manga title please let me know <3.

Is a school life genre, and there was a setting where 2 high school students were sitting on their school's roof top, and the taller persistent kid (seme) hits on his school mate (uke). From there they start going out. The story goes from High school to them entering University and the uke reaches a growth spurt attracting many females and soon after the uke wants to switch rolls with the seme in order to loose his V card. But the seme always refuses to switch. On campus a female fellow-student askes the seme if he could help her land the uke as her boyfriend, but she doesn't know that they are lovers. Tho the seme agrees to help her because he wants the uke to be the tachi for once. Yet the seme is scared that he might loose his lover (uke) to his female friend. At the end, the uke looses his virginity to the seme who becomes the neko.
