1. I think one of the guys was either at work or on the way to/from work and his partner calls to have phone sex he asks if he can wait, then teases the guy then hangs up.

2. guy was sick as a child, his sister died when his mom ran her over when needing to take him to the hospital on a rainy night and he had to pretend to be her after. Later finds the guy who used to say he would save her but when he found out it was a guy he ran away.

I don't know the first one but the second one is Hatsukoi
