Adult version. The story proceeds under the premise that he never confessed back when they were in elementary school!
Yuito was a noisy little brat.
But when Yuito came over to the house after so long, I was shocked! He was already a fine young man.

"I missed you since I couldn't see you at all, y'know? lol... Wait, did you get shorter?... lol"

........Guess he hasn't changed that much after all, huh?!
No, he has changed, but I'm being teased! 😭
