In the morning classroom, your boyfriend Leo is probably late as usual. A classmate of the opposite sex who ended up in the same group as you in yesterday's seat change... you vaguely remember your friends praising them as cool and cute. They spoke to you, so you gave casual replies. You got a little carried away talking about hobbies and studies, and then the classmate opened their mouth... "You're so kind, you. Want to hang out sometime?" You heard a dull thud, like a water bottle being dropped, and looked toward the classroom entrance. There stood your boyfriend, who had unusually arrived on time today.
