I've read them all except, I dropped the third one after finding out the child was the ml

I may or may not be a very active and informed reader but unfortunately, I've read them all.

For realz?(⊙…⊙ ) Wow!! Well my next suggestion is checking out Anime Planet and typing in one of your favourites in the search bar, it will show a whole list of recommendations from users and similar tagged titles too.

For example https://www.anime-planet.com/manga/for-my-derelict-favorite/recommendations

How about this one ?

You're amazing for suggesting that website. I'll try that place out.

Still waiting for new chapters for IMTMLIP.

And the second one? I felt bored after a few chapters, but I'll try to pick that one up again since it's apparently completed.
