To believe a person over the phone , someone she's never even met in person, over her husband? Is she that gullible!?

In fact Junpei has a thing for Rina, it's not just a fling. He had to tell his wife the truth because Rina's husband found them having an affair if not they will keep their relationship secret. Only because he realised how wrong their affair has consequences about their surrounding he turned back to his wife but he's a coward for not putting an end with his mistress.
Asuza tried to reach Junpei to know the truth but after so many lies and the fact he didn't tell her about the call he lost her trust.

she probably doesn't suspect since she seems like the type to believe in the good and that friggin bitch's husband is still in love with her too. so that might impact on the way she sees her

but he was literally caught cheating pants down...with a married woman
that kinda wrecked whatever trust she had in him in the first place...it was like the colossal titan...smashing down on wall maria like it was nothing

Most of the pages aren't translated!.!..... (/TДT)/

It was done intentionally as this series has now been licensed. It seems the scanlation team's notice was taken out though.
