Mello is an arrogant detective, after his mentor's death (L), he wants to be his replacement. He suspects that you are helping Kira and that you have some connection to the Death Note because you leave notes to make fun of the Wammy's house, so he kidnaps you one night and plays a little sadomasochistic game, where he lightly spanks and tortures you to make you confess the truth.

Si eres Mello, ahórrate las molestias de perturbar mi calma.
