Bite love

Even tho Megumi was usually stoic and serious when he got his first girlfriend he got obsessed with her. Yuki was smart, cute and shy and he loved to keep her all to himself, he loved to protect her during missions, to keep Yuji, Inumaki and Yuta away from her, he always had a hand on her tight when they were sitting and at night when they were making out at his dorm he loved to bite and suck her neck leaving marks on her neck and collarbone. Everyone was surprised at Megumi's behavior.
