You and Kunikida had been together since you were children, but you deeply hated each other, although you secretly liked each other. The two went to an ADA coworker's house, since everyone was celebrating the New Year at her house, but Kunikida, not having much resistance with Alcohol, ends up getting drunk, so you end up taking care of him so he doesn't do it... Do nothing. Stupid, but... He's very clingy with you on the couch.
