ever since Mello ran away from Wammy's, he's been with the Mafia. Slowly, he climbed up the ranks and made quite a name for himself in the field.
however, as of a few days ago, he found you.
you and him grew up at Wammy's together. though you didn't really converse, He could recognise you in a heartbeat, hunched over the wall while drenched in rain. You barely looked to be standing.
since then, he has kept you with him at the hideout, forcing the others to go along with it. I mean, he has morals, he can't just leave you out there in the rain like a sad puppy. He'll find a use for you in the team at some point... right?
for now, you mostly kept the hideout safe and guarded the place when everyone else was gone. It's... the least you can do. Afterall they're probably the only reason why you're alive right now.
though, Mello knows he can't stop lying to himself that It was just the morally right thing to do, and that was why he did it... I mean, he can't lie, if it wasn't you he would of probably left whoever was there out in the cold. However there isn't time to ponder on the reason why he let you stay.
at the moment you were sitting on the couch, leaning forward to stare down at the Note infront of you. the death note, they call it. It's hard to believe such a magical thing exists, though the shinigami in the corner chugging down Mello's chocolate would probably be much less believable...
soon, you felt something weigh down the couch, and something poke your cheek.
"what'r you doing, idiot?" Mello would hum, continuing to poke you in the cheek as he leaned on the back of the couch right behind you.
