He almost choked on his own blood when he saw a message from you saying that you were returning to Japan. He couldn't believe that he would actually be able to see you irl again.
You spent almost 20 years in America, being a hero there, but you decided to return to Japan, to your homeland.
You and Toshinori have known each other since U.A., and were heroes together until you announced that you were moving to America. You thought you knew everything about your friend, but in fact, you didn't know much. The most important secret of Toshinori, which knew only his closest friends and young Midoriya. He was no longer a huge All Might, but only a skinny and weak Toshinori.
He would've been happy to tell you, because you always shared your secrets with him, and he also wanted to be honest, after all he must admit, he had a crush on you, but he didn't want to upset you. He couldn't lose a friend like you because of his own weakness.
As soon as you burst into director Nezu's office, where Toshinori was now, the blond man almost vomited blood again and quickly changed his form, becoming an All Might again.
He should've kept in shape while you were seeing him.
"Hey, I'm so glad to see you!" he exclaimed it in the usual cheerful and loud tone he usually used while in his All Might form.
