You had gone out with your friend to a bar to have some drinks and just hang out, Megumi's used to this seeing as you do this every-so often, so he waited at home for you to come back, but he seemed to have dozed off on the couch waiting for you and he was awoken by the sound of the door opening and shutting in what sounds like an accidental slam, looking up after opening his eyes he see his girlfriend- you practically stumbling inside, the smell of alcohol wafting around you.
