Toshinori Yagi/All Might:

He blushed as you entered, his blush growing bigger when Midnight looked at him with a smirk. He was quick to get up and hurry to you, pulling you out the room before the others can tease him, nervously asking you why you are here, asking if something is wrong. When you said he forgot his medicine, he gasped, realizing he indeed did before he thanked you, taking it from your hands with a smile. When you left, he heard Mic mock the way he said thank you in that voice that clearly said he's deep in love so he blushed and hurried back inside to get back to work.

Shota Aizwawa/Eraser Head:

When you entered, he calmly asked why you are here. When you held out his sleeping bag, saying he forgot it, he hummed, taking it, thanking you for bringing it all the way to his work. When he heard Mic and Midnight wolf whistle, his head was quick to snap to them with glaring eyes and his hair floating so the two shut up. He calmly looked back at you, thanking you again before going to his desk to continue typing some paperwork.

Hizashi Yamda/Present Mic:

When he saw you enter, he excitedly said your name before asking why you are here. When you said he forgot his lunch box, he gave you a big hug, saying you are such a help before he took the box, excitedly telling Eraser to look whose here. Eraser just gave you a nod as a greeting, thinking that Mic looks like a kid showing off their favorite thing.

Nemuri Kayama/Midnight:

As she was at work, she realized she forgot to do her eyeliner and it was annoying her so she texted you, asking you to bring it. When you arrived, she happily thanked you, wrapping her arm around you and dragging you the toilets. She talked to you as she put the eyeliner on. When she was done, she gave you a kiss, thanking you for going through the trouble to bring it.

Keigo Takami/Hawks:

He forgot his jacket so he stood closely to Endeavor for his warmth, who was angrily telling him not to stand so close before he fell silent and narrowed his eyes at the door so Hawks looked before excitedly saying your name, rushing to you and hugging you before he asked you why you are here. When you held up his jacket, saying he forgot it, he gasped before hugging you again, saying you are a lifesaver before he happily pulled his jacket on. When he could feel Endeavor glaring holes into the back of his head, clearly getting impatient, he smiled and thanked you again before saying he has to get back to work.
