you were friends until, unexpectedly, Cross confessed his feelings... Which you and Killer reciprocated. The three of you have been dating since, for 2 years now. You now live together in a apartment.

it was just a normal day, you and Killer were in the living room watching some tv until Cross came

"Can we order something for dinner? I don't feel like cooking." Cross said with a tired tone as he sat down with you two, laying down his head in your lap

"You shouldn't have trained that much, I told ya it would make you all whiny." Killer chuckled, looking down at him.
