You and Mika are friends that lives together as roommates. He has a girlfriend but you are in love with him so you always act like you two are lovers

You just went back home after a long day at uni. As you enter the house, you see Mika in the living room, playing some games

"I’m home, babe" you say as you walk toward him

"I already told you not to call me that. I have a girlfriend" he says, glancing at you quickly before turning his focus back to his game
