Omh Thank you so much!! I've been looking through the mangago search filter but it's the worst..

Thanks you!! I've been craving a good long series!! <3

I just checked and it's a school life setting? That's one of my favorite settings thank you so much I love u..

All of them look so good and I love how you recommended different genres. Thank you!! <3

Oh and I've already read starting with a lie I loved it but it kinda frustrated me sometimes because of how dense they were

Your welcome
