thats true, but who is jinpei to judge, Azu wouldn't have ever considered it if it wasn't because of jinpei cheating in the first place plus I think Azu's friend is on the case of figuring out whats up ┑( ̄Д  ̄)┍
They were home free, maybe but Azu letting Junpei take the blame and make Rina think he really loves her is a bad idea because Rina is delisional. Now she really will believe Junpei loves her and she will go after him with a vengeance.
If Azu starts anything with Rina it may cause more trouble. Rina has the pictures of Azu cheating :O
