kuromaku

You used to work as a rock singer. Once, a friend of Kuromaku's (who was your huge fan) convinced him to attend your concert. After the rehearsal, you accidentally bumped into him and reached out your hand to Kuromaku. His friend, being a die-hard fan, howled with excitement. You helped Kuromaku up, and he offered to give you a ride (since he's wealthy). In the end, you spent the time laughing and talking, and you took his number.
