Otona nya Koi no Shikata ga Wakaranee! – Episode 4 (RAW)

Bonding over movies during a late night at work, Mio misses the last train and ends up staying over at Mashima's place. Seeing the "real" him in casual clothes, Mio feels a warm, domestic flutter. However, the mood shifts when Mashima accidentally trips, landing on top of her on the bed. As he tries to pull away, Mio stops him, asking him to hold her and stay the night.
