damn I just noticed your comments from back in September lol, I just re-read it recently so I hope you either found it already or I was helpful in sharing

I am willing to wait no matter how long since I've been looking for it for a year already HAHAHA that's why I'm so grateful that you even noticed and linked the manga here tysm!!
I'm glad I could help the year long search to finding it come to and end, I am also the type who is willing to search until I find a mange so I understand the struggle!
You're very welcome (˶◜ᵕ◝˶)
what's even crazy I knew the art style is familiar and when I clicked on it I saw that it's one of the author's work that I love It was just right under my nose I just didn't know
The last page on chapter 3?? I've been looking for it's manga....if it has one
