Karin begs Kenta to keep her nosebleeds a secret. He does so, even cleaning up her mess. Karin is left perplexed as to why her blood increases faster around him. Ren explains vampires are drawn to victims with a trait appealing to them; Ren likes stress, their mother likes lies. Karin is drawn next to (unknown to her) Kenta's mom and bites her; unfortunately, Kenta glimpses this. Karin learns her blood affinity is misery, and being around unhappy people increases her blood; thus she resolves to try making Kenta happy as possible.
