For quick clarification because I think I did a disservice by being a tad bit overdramatic:
I thought it was a beach arc but it was just beach chapter (that being the latest one Ch.60)
There are indeed a frick ton of love interests but fan service is rather minimal and the ratio of them being actual simps to being real characters is I'd say 1:4
Just felt a little guilty but there being an increasing amount of girls does annoy me so do with that information what you will
This was actually a surprisingly fun read. I was going to drop it when I found out it was the FL who falls in love first, but I decided to give it a chance and I wasn't disappointed. I ended up shipping them in the end. And the harem also surprisingly doesn't annoy me. It might be because they act more like family rather than love interests in the story. At least, that's how their interactions feel like to me.
Like the first girl feels like his younger sister.
The second girl is like the mom/housekeeper.
Third girl is the medic. No romantic tension or anything. ML saved her and sent her and her bro to school. They just go to school 70% of the time haha
Fourth girl just wants to destroy things
Fifth girl is a witch and doesn't really do much/plot device auntie
Sixth girl ships ML with FL.
And seventh girl is just a child ML rescue from a cult. I think she's just grateful to ML.
So far, it's pretty chill. A few moments though where the characters blush here and there but I think those moments could be counted with one hand. The romance is mostly focused around ML and FL

Ah a beach arc... with like 10 women that have a crush on the MC...
