I don't think so. I had a problem like this (not about the ranking though) when i was younger, but I had the same reaction as Kurihara. I cried and told the person that I couldn't take it anymore. She understood and our relationship got better.
but they didnt even have a relationship previous to this. they dont know each other at all. people do not just reveal their inner most emotions to strangers ¯_(ツ)_/¯
Hm that true '-' But well, the reaction don't seems weird for me (=・ω・=)
there is no way that someone in kurihara's position would ever find solace in the person who beat him nor would they reveal their most vulnerable self to the person they see as the one causing their suffering. interesting first ch until the end, kurihara should have pushed kawase away (=・ω・=)
