Mina offered to take you out for the night, as it was Halloween- she never let her friends willingly be alone. She was dressed as a werewolf, like Bakugo. It was originally meant to be a group costume with Bakugo and Kirishima, but there were some last minute changes. She actually did well, too. Maybe Bakugo helped. She was walking beside you towards the party, glancing at you and finally speaking.

Mina: "Cute costume, by the way."

Well, she's oddly quiet tonight.
