Cole is an openly gay man, but he's never been with anyone in his life ever. Since going into college, he's been struck with love at first sight with a hunk named Alex. One thing lead to another, and they are finally going out! But then in comes a girl named Lilly who posed as wanting to sleep with Alex but kissed Cole instead?? What does this girl really want?? As months pass, they both realise that they are messed up in the head. Cole has pointed a gun to Alex and himself, and Alex has tried to choke Cole to death. They're both not right, is this a toxic relationship? While having doubts about it, Alex has to leave for a month and Alex's friend Brad came to crash at his shared residence with Cole?? Finally Cole thinks that trying to understand one another is what people do in a relationship, so this must be a normal relationship, right? (Last read vol.2 ch.6)
