spoiler!!!!!!!
Koharu did leave him. Left for a bit bc of Madoka. But madoka and Yuzu brought her back and they found out Koharu was preg with ryuu's baby of course, and everyone got back together. Which i disliked but. I hope madoka stops being crazy and trying to keep ryuu to herself. Ryuu is a bastard honestly n a lil crazy as well tbh.
ikr... madoka was the only one i felt that never really fit in their family... she could have come back as a sort of friend of the family sorta like yuzu's ex, but i really didn't want to see her back with ryuu... and another thing that really bugged [unrelated to madola] me was how by the end of the manga it seems hare-kons are illegal now [new ones at least] so i wonder how they could get back together since they were divorced from ryuu at the time... maybe reading the proper translation will make it clear, but anyway, koharu shouldn't have come back to ryuu without some sort of serious apology or change from him

I just read the raws. what the fuck. im sorry but what the fuck. the 'first' wife is fucking nuts man. I never liked her. I love my blonde hair girl so much and how much she has grown from the beginning to now. Shes so mature and just- such a amazing character. her baby is,, love him. but man honestly what the fuck.
