UGH I just have to know the second one... TT.TT reply
1) MANGA The seme is popular. He has blonde hair. He rides on a train and saw the fluffy uke. Uke was playing a game. Seme plays the same game to be closer with uke. What the seme didn't know was that uke was also interested in seme. Seme and uke go on the same school. Seme is senpai and uke is kouhai.
2) MANHWA I only read the first chapter ages ago and told myself I'm gonna read it later. BUT I FOGOT THE TITLE HELP The uke has pink hair. Chapter 1, it was raining. Uke was beat up and chased by bad guys (mafia? gang?). The seme happened to be parked nearby. Uke rans to seme's car... I'm not sure now, but I think they didn't know each other. Uke just go "help!" and ran inside ther car...?
