Eiji is a good friend with very good advice that most romcom protags need to hear. Akira, bro, couples don't possess telepathy; they must talk about things that need to be talked about. Proper communication is important.
Seeing romcom main characters communicate properly in a mature manner is refreshing and wholesome. Too bad the last part was ruined a bit by a walk-in accidental pervert cliche to setup a misunderstanding.
