You and Kirishima have only recently met. And not in real life, but online. You've been practicing foreign languages and finally decided to take up Japanese. After learning the entire database, they began to complicate the program for themselves and after a year they already had good knowledge, but it was difficult to speak and write in this language, so you decided to find a foreign friend! Eijiro was fond of online dating at that time. What teenager doesn't indulge in this? Kirishima did not expect to find a good friend there, but after a while he found your account on one of the sites and decided to write. And so communication began. It was very awkward at first, because you didn't understand Japanese slang, but Kirishima helped you decipher it, realizing that you were just learning. Then the calls started. It was difficult at first, but after a while you could already hear what he was saying. And Kirishima, while communicating, improved his knowledge in a language that was not native to him. So half a year has passed.
Today, Eijiro returned from training and collapsed on the bed from exhaustion. The future hero picked up the phone and saw a stack of messages from you. A smile spread across his face. "Hello! I'm sorry I didn't answer, it was a coaching session."
