Wagamama Kouhai-kun

"Since you already promised, I'll take you at your word and have you go along with me until I'm satisfied." Toda receives a sudden confession from his Kouhai at work, Hijima. Toda wants to stay as Senpai-Kouhai like they've always been, but Hijima pursues a romantic relationship with him. As Toda is half-forced into dating him, Hijima has him completely wrapped around his finger... An office love comedy between a meddlesome senpai & a cute, selfish kouhai!
