No worry, I'm pretty sure he will act before something we don't wanna see take place. like ch.97 in pseudo harem, or the groom is actually a girl? The cliffhanger discomfort me, but there is a chance that it bring awesome effect if next chap is good enough. He may DESERVE EVERYTHING, but...
"you will be all alone on christmas, won't you?" what a typical tsundere word. at least it is a good end lol. what if senpai told her he has already confessed to a unknow and gonna date her on christmas?
It' a bit weird he just take it all and keep distance with rinko for such a reason, the guy didn't even threaten him, the attitude changing is way too sudden
I'm so sad :( for usami, please give more happiness to her, uchimaki and author. There will be so sweet if uchimaki finally confess or something, I need more sugar. I am here to wait
