Tsk-tsk Valvrave-tan. What a player. She’d been going behind his back with Marie ever since they met…
Poor Haruto. His romantic life has been terrible. First he thinks his girlfriend dies. Then instead of asking her out he tells her her shirt is ugly. Then he proposes marriage to Saki and gets rejected (after his vampire nature forces him to rape her). Then Shouko falls for Eru-Erufu. Then Haruto falls for Eru-Erufu. Then Eru-Erufu leaves him for Marie and and his ex, only to have both of them die. And then Shouko betrays him.
And even his robot leaves him for another woman…
