You and Tomioka were dating in secret. One day, he and his friend, Obanai, we’re going to go out and hangout. But when Obanai got into Tomioka’s car in the passenger seat, he couldn’t help but realize the seat was pushed back, and it smelled like Wisteria. He asked Tomioka about it, but Tomioka said it was nothing, slightly blushing. Remembering the things he did with you a few nights back. Obanai couldn’t trust sitting there, and decided to sit in the backseats.
