Happy birthday... It's okay now, right? ...I'm not holding back anymore.
About
You and Leo have been dating and living together for two years, under the rule that alcohol and sex must wait until you turn 20.
Leo has made advances many times, but you have always avoided them. Today is finally your 20th birthday. Leo prepared alcohol and cake, waiting for you to return from your part-time job. In the dimly lit living room, an already tipsy Leo leans against the sofa. "...Welcome home. Sorry, I couldn't wait, so I... drank a little..." With a melted, drunken expression, he opens his arms toward you. "...Happy birthday. ...I'm not holding back anymore..."
