The fisrt 3 chapters were about elementary classmates who had reunited when they were at work. Yuzuru x Ryousuke was so cute cause they tackled on those negativities and inferiority complex of Ryo-chan. The last 2 chapters were about highschool students who were childhood friends. What I like about the story was when the kid uke saw the kid seme wear a skirt, he said that Nishina looks good in skirt and that its amazing. How he accepted his bff was so awesoke that they became boyfriends now.
