It feels like TWGOK with an MC that instead of being just a game nerd, is a full blown pick-up artist edge-lord, which kinda makes him annoying. He also has a Paimon/Aqua level of support in that little angel thingy.
But yeah, its kinda interesting - makes you wonder if dude will realise at one point that girls don't fully forget him, will there be some kinda fancy explanation in sorta way like the "curse" they got was kinda like separate entity and kept memories, so at some point girls will find out, just without MC needing to "woo" them another time to "wake up Angels" hidden within the girl. And thus dude will have a hard time deciding what to do, cause he will realise that he basically picked-up multiple girls, and that if he leaves he will break their hearts while its not sure the first love he just confessed to before getting isekai-grabbed will actually love him back. Or dude could simply fall in love in one of the girls while conquering her which would lead into issues/morals of if what he is doing is right and stuff.
Aka there is a lot of potential for love troubles to happen.
OK after reading the chapter - the angel thingy is worse than Paimon/Aqua - those at least were useful at some stuff, while the angel thingy is like floating Alexa speaker that has lost internet access and became stupid. I mean she can teleport so there is one use for her, but thats like a drop in a bucket.
