How is this anime so bad but so watchable? It's not "so bad it's good" either where enjoyment is gained from the lack of quality itself. No, it's something else. It's as if it's watchable and comfy in spite of being terrible, and wasting its own premise even right at the beginning. Wouldn't it have been more logical for the protag to have originally been handsome and then have to become ugly in the isekai world? Also, having it be that he can't touch girls seems at odds with the social penalty of being ugly. Getting hurt if you touch girls and exploding if you have sex seems like it's own separate premise that would fit better with an ikemen player type who is given incredible powers in exchange for it. That way, the character would go through anguish and the trade off would be a real penalty that affects the story.
Saying all of that bullcrap, I somehow don't care and want to keep watching to see what happens. I'm watching this incredibly generic cardboard cut out anime where the only premise is that there's a big fat ugly guy who's harmed by touching women, and absolutely nothing of consequence happens (things have the superficial appearance of happening but don't have consequences or are resolved immediately), but somehow I like it.
