Ramon is very popular among the female populace, not neccessarily restricted to vampires and due to his status he is obliged to accept some invitations that obviously aim for him. Minaho got sick of it and went to such an occasion and busts a ladies try to lay Ramon. Ramon happily joins in on the prvocation since he hates attending such events.

That is why the colors turned so bright, lol. Neither Ramon nor Minaho prefer bright colors for their love-nest.
