《Emotional Experience》

Itosh rin a person who doesn't know how to express his feelings suddenly find himself interested in isagi.

A month or so something changes which upset isagi. Rin finds interested in nagi. Thanks to isagi, who made them reunited since they last saw each other at blue lock.

This was different, but he was still not good at showing his feelings. He was hoping for isagi, who he was talking to would help him, but it seems nagi is more interesting.

Thus made rin cheat with nagi isagi friend, even though him and isagi are just talking nagi drew him in.

Nagi was also in a relationship with reo, reo didn't know that nagi was cheating on him with rin nor knows that nagi was about to break up with him to be together with rin.

"I thought we were doing fine." Isagi has tears going down his cheeks. "You even told me to wait for you."

"I know, and that was very." Rin couldn't find the word at how uncomfortable he is feeling. "I shouldn't have said that.. my apologies."

Isagi stood there watching rin walk off with nagi who is holding rin's hands.
