Cute, both of them.
The first couple, the seme is actually a nice and cool guy. He just need a little push. Tbh I didn't expect the uke to have a crush on him because he's always has a poker face all the time.
The second couple, wow, Reiji has grown up well. He's sooooo hot!! I thought it's going to be a heavy drama but no, he suddenly said he's gonna stop running away, wowww so cool.
By the way, Izumi woke up like an alarm clock is hilarious. Both uke are such a tsundere
Thooo 4 star since it involves cheating ⊂((・▽・))⊃
