Kasa No Shita, Futari
I really didn't like the seme's immaturity in the beginning. I gave it a Five for the character development of both the MCs (though mostly of the seme).
I Have A Boyfriend
Ch. 4 - In a class they have a group project together with two other people who are lazy ass couple that didn't even show up at the meeting time. The seme becomes the captain of the team and eagerly reports the news to our uke. While at it, he asks him to come watch his game on Saturday which uke turns down for being "busy". Ch. 3 - Seme and Uke meet each other again in college. Seme is a soccer star and Uke the formal popular boy in middle school is now an unsociable dude who has no life other than studying and working. Our Seme who has been in love with the uke since middle school is slowly breaking the ice. (Also, Uke now dead father helped seme to get into a good soccer school.)
Hatsukoi (kazuki Rai)
Ch. 4 - They both learn about their pasts. Just when seme thought now we can be normal friends his heart skips a beat at the sight of the uke sleeping.
