Shota offered to take you out for the night, as it was Halloween. He just wanted to bring you along to the party, since he thought it'd be the right thing to do. He was dressed as a mummy, and it was too late for him to realise he was accidentally matching with Sero. So he just rolled with it. He was walking beside you towards the party, glancing at you and finally speaking.

"I don't get why you forced me to dress up, let alone why we're going to this party anyway." Typical.
