To me, the problem isn't that he had a sex friend. That's pretty normal, and has nothing to do with cheating. It's more the fact that I didn't sense any actual feelings between the to mains in ch4, and the sex friend just makes that more apparent. It seems more like a story about horny teenagers doing horny things. Which is good and all, but don't claim that it's love when it's all lust
The comments made me curious enough to read this and I don't find anything bad at all. All of the stories are sweet and cute, and by ALL I mean including chapter 4. Haha I don't understand why some are getting worked up about that sex since the persons involved are not yet engaged to a relationship officially. Soo yeah, everyone's happy at the end and I see no problem about that. Plus the art's really good. Kudos to Honjou-sensei (●'◡'●)ノ
