RATE: 7/10
There were multiple stories in this. The first story was about a loner hanging out with another guy who had a child. The child's parents died when he was young so his parent's friend took care of him. Soon enough they started dating and finally moved in together. The second story was about a high schooler trying to figure out his sexuality. He starts dating his friend's older brother's ex-boyfriend who's in college soon later. I don't know what happened in the 3rd story since I didn't read it, but I didn't like this manga a lot, but I'll recommend it.
