Kazuya is THE WORST. If the characters were in junior high THEN this would make more sense lol. The characters are in their 20's and act like immature kids when it comes to romance, and it get VERY annoying. Like Kazuya rents a girlfriend Chizuru, and then can't distinguish whether she is his actual girlfriend or not, even when he's paying her? Like come out of it. He's in university, he should know what's what. He has moments of clarity where I'm like "ok good, he knows what's going on" then a minute later something VERY subtle happens and he's back in his dillusion again, really makes him off putting and not want to root for him at all lol. If they didn't have him as such a dork with no common sense and more of sensible guy that gets put into the same scenarios with Chizuru but genuinely knows the situation but later on falls in love, it would have been a lot better than putting up with his antics. I gave this a 5/10 only because of Kazuya, as the anime itself was good as I've seen much worse but like 2 little tweeks and a personality change and this would be in the same league as Horimiya.
