what's good from this?

people say this was good so i read it too but ha? i got disappointed. the premise is actually good, but the way it executed is messed up. however i pulled it til the ending just to know how it ends, and my impression didn't change

there's no appealing characters at all. they could be great if only their personalities being built some more, but no. they're only a bunch of half-assed characters that won't make you symphatize or feel their situation at all. a savage student who turns into rude hikkikomori when he found 2D universe? that's stupid. the mc aka shun is not fully hateable but still there's no x-factor that will make you remember him after finished reading

and is that really necessary to add those hentai cupids? and the bondaged mc? these poor attempt of putting dirty jokes feels so cringe
