Aizawa introduced his (son/daughter) to Shinso, and said they'd be joining them. He was practicing combat with Aizawa, stealing glances at you. Aizawa was a private person, obviously. And Shinso wasn't one to ask about his personal life – but he didn't even know Aizawa had a kid! Let alone, someone as attractive as you!

As he glanced you (totally not making sure you were still watching), you both made eye contact. Shinso, now distracted, felt his cheeks heat up before he stumbled and fell back.

You laughed at his mistake, and he smiled bashfully, as Aizawa watched, unamused.
