"Damn, turning her down because I literally just started another relationship was pretty cruel of me, huh."
"Why didn't you tell me you DIDN'T date her? You're sleeping on the couch tonight!"

I don't know why the story keeps pretending that Tamura rejected Ichinose due to not liking her when it's simply because he already have a girlfriend. It wants to keep the vibe that Tamura made an error but it's not believable when he has a legitimate reason to do so. I don't even know why bother with a setting like this, Tamura is made to look like a good guy for not cheating on his 1 day old girlfriend but what is even the point when dude easily folded at Ichinose's seduction. I know it's hentai, it doesn't have to be deep, but it could have been entertaining as seinen, where MC is stuck between remaining loyal to his long relationship and expect stable life with moral intact, or throwing it away indulging with this chick you used to know and become big and desirable, but the way she seduce him is toxic or shows she hasn't really grown up as person, so you expect it's going to be a slow dumpster fire of a relationship. That reminds me, there's a webtoon that has similar plot, Drug Candy, though it involves a married man and a younger girl with a screw loose.
