When I read the first chapter, it seemed quite interesting.
Having the girl that stole your girlfriend trying to hook up with you is such an out of left field concept that it hooked me up immediately out of curiosity on how over the top this series would be. Something comedic like 100 Girlfriends but with only two girls, or something outlandish like Gal☆Cleaning's 8.XX chapters would have been perfect for this concept, just balls to walls.
BUT THIS IS SO SAFE IT HURTS!!! There's nothing interesting going on here, he just goes on a date with the girl and there's very little animosity between them and they go through all the dating cliches like it's filling checkboxes! The guy isn't just a pushover, he's also boring to accompany!
Why is the girl so interested in him in the first place? There's nothing interesting about him - he isn't bright and fun to be around like a shounen protagonist, he isn't depressing and mysterious like Shadow the Hedgehog, he isn't naive and full of dreams and hopes to the point of activating her motherly instincts like Bell Cranel, he's more like that stupid guy with the smartphone in another world without the smartphone or the other world or the "so bad it's entertaining to rip apart" factor that Kirito has!
This guy is just a bunch of nothingness! I understand the girlfriend dumping him, but the other one wanting him?!
I'm sorry but this manga started losing me on the second chapter, it's the 5th now and I'm bored.
Have fun everyone who decided to stay and read through, I'll take my leave here.
