Oshiete, Ookami-san.
Multiple stories: childhood friends who fall in love, a guy who intentionally tries to make straight guys fall for him and then falls for a gay man he accidentally seduces, a couple who role plays to spice things up.
I Hate
Two sets of childhood friends reunite five years later.
Portrait (natsume Kazuki)
Aoi struggles to suppress his feelings for his best friend, a photographer he has known since childhood and who has been like an older brother to him.
Like That
Aizawa has loved Tsuji since they were in school. Tsuji, who is dependent on Aizawa, is uncertain about his feelings until he fears Aizawa might reconcile with an ex-girlfriend, so they begin dating. A few months later, as things are turning into real love for Tsuji, Aizawa breaks off their relationship without explanation and moves, leaving Tsuji heartbroken. But for the first time in his life, Tsuji isn't willing to let someone go. I was frustrated by the breakup, because communication would have cleared up the issue. You don't just leave someone. But Aizawa never believed that Tsuji loved him until that point, so I believe he thought only his heart was truly on the line, and that he was doing Tsuji a favor by making a clean break. I love how much Tsuji grows across these stories. This author is wonderful about continuity.
