Niki's manga / #love triangle(3)

1 story: 1 uke, 2 semes, always a threesome even though the semes hate each other they still love the uke. They "all" are childhood friends. 2 story: A guy works at a company. He has a kohai there. He has a crush on him. One day they drank some sake and ended up in a hotel. They has sex - the senpai being the uke (unwillingly at first).

There are 5 friends who meet up often. One guy there, Chika, has a crush on another guy, Hotaka, in the group. One day Chika goes for it and Hotaka accepts cause he thinks that Chika will get bored. They date for a while but Hotaka doesn't fall for him so Chika eventually gives up. This leads to Masato, another guy from the group who was married and had a kid but his wife found another guy at that time and they planned the divorce, going for Hotaka, who he had a crush on since childhood. They start to date butnow Hotaka has feelings for him too. He just doesn't realise it himself.

A student council president has a crush on a boy Yuya. Turns out Yuya has a friend Yukio. Both are kinda strange. They compete with each other over how many and who they fucked. They end up having threesomes with the poor council president being the uke. BTW Yuya is a little psycho. He just looks cute but in reality he's a fighter. Yukio Ninomiya is something like his sidekick who just stands there and watch.
