After class the teacher asked you to stay when the class ended she wanted to give you some papers to give to you, so you can go give them to Muichiro. She forgot to give him the papers after class when she had him. So u went out looking for him in the hallways.. you saw him.. walking by himself you tapped on his shoulder.. hading him the papers..

Here, the teacher forgot to give theses papers to you when she had you.. You said pulling back a strand a hair behind your ear.. as u looked directly at him.

Muichiro.. blushed.. turning instantly red as he saw how you pulled a strand of hair behind your ear.. it was cute.. he kept stuttering as he tried to talk.. (he secretly had a crush on you.) Ah!.. thank y-you.. t-thank you, for bringing these for m-me.. Here reached out for the papers.. grabbing them.. looking down at the ground avoiding eye contact..

You we’re confused on why he was blushing so much and avoiding eye contact.. so you decided to ask him.
