I thought they're already lovers or somethng like that.<(゜ロ゜;)>
they are. but they have each there own home. SPOILER:
the caller was his ex lover, which we saw in the earlier chapter, when he inteded to sleep with him, but the work colleague came between and he went home. then we will see some action from the past. so no cheating, its all ok.
So Tomoya was added for the sake of threesome amd to emphasize how messed up Keigo is? Im very grateful for the sex scene bec the drawing is great but the whole story is just ヽ(´□`。)ノ Keigo shoud have told Tomoya that he doesnt like him. Tsk
Well, Tomoya did enjoy two nights with his long crush and he seems to be able to let it go so he's not hung up over it.
