Can anyone tell me the name of this yaoi manga?
There was this manga I had read about a short high school boy with black hair.
He had caught the eye of a tall blonde hair boy (a schoolmate or a classmate).
They would talk a lot in the school roof top. They started going out as lovers.
The short kid with black hair is the uke, and the tall kid with blonde hair is the seme.
But when they entered college the uke was suddenly much taller and manlier than the seme.
Girls would gawk at the now manly uke. Leaving the seme to seldom grow insecure of their relationship. In their bedroom, the seme and uke would bicker during sex because the tall uke wants to top for once and become a real man. Then the seme tries to push the uke towards a girl he knows in college even though he is worried that he might lose the uke to the girl. But in the end of the story the seme takes up the bottom roll for the uke to loose his virginity and become a man. That's all I remember.

a japanese Yaoi School Life manga made during or before 2010 which has inter-linked-stories/collections-of-stories, & the first main story is a sensei & student trope with a high-school-doctor/teacher & his lover who is a high-school student & in the second story in the same high-school setting is based on a student & student trope with a tough looking high-school delinquent seme who has medium length light hair & wears his school-uniform-shirt open & over a t-shirt & the seme is friends with the boy from the first story & seme is also taller than the timid high-school uke who has dark hair & wears a neatly school-uniform & they meet up at the school-rooftop & begin a romantic relation, there is a time-skip/time-jump that on the after-story extra chapter where this couple arrive at the college entry & both the seme & uke appear to be much older-looking, but the still timid uke had a growth-spurt that makes him much taller & muscular than the seme & turning college-girls' heads on campus & one day during intercourse in their bedroom, the uke confesses that he hates still being a virgin, more so now that he is manlier than the seme & he wants to have sex like real men do & the seme starts planning to get a college-girl to deflower the uke, then the seme goes to talk to his college-female-friend who likes the uke but she does not know that they are boyfriends & seme loses his confidence in asking her because he doesn't believe that he could keep his boyfriend after the uke sleeps with her & in the end the seme decides to become a uke for the first time and allow his uke lover become a real man
