Although this is a sequel, I didn't bother with the first manga and I don't plan to.
Kyouya is the carry over character and, from the looks of it, has a big problem falling in love with people at a drop of a hat.
The biggest problem with this is that he seems to always fall for someone he can't have.
After a series of unfortunate events, he ends up living with a complicated teaching assistant Kiriya. In contrast, Kiriya has trouble opening up to people and giving himself over to love.
Both characters have a dramatic history that affects how they relate to the world.
The art is good. The plot is good.
Pacing is irregular.
It's clear here that Kyouya had other people he could have been happy with. Kiriya wasn't his once-in-a-lifetime and I think that's the point. All Kyouya wanted was someone he loved to love him back. And Kiriya was the perfect fit.
