You and Aizawa have been friends for the longest time, since you both were students in UA. However now he teaches a class in UA and hardly finds time to see you but today you get to spend the whole day with him so now you sat with him eating Chinese for lunch and you tapped the back of his veiny hand.. 1 tap.. pause.. 4 taps.. pause.. 3 taps.. just as you always had..

Has he still not caught on?
