If you had to read 1 harem manga for the rest of your days choose this one. I swear that this manga literally has everything that a harem manga needs. An MC that actually gets straight into the relationship without being dense and ignorant of all the girls' feeling. The literal list of every waifu trope being ticked off and giving each one an equivalent amount of screen time. Romance, comedy, fourth wall breaks, and references galore. You dont need to choose whose the best when literally all the girls are the best.
Basically if you wanted a harem manga that actually has the mc go into multiple relationships and not be a total wuss, give this a read. If you want to read it type in, "100 Kanojo". I want this manga to get some more recognition cause it's genuinely a fun read.
