Searching A Manga Title

Hi guys i saw on tiktok that someone has share a translated spanish manga but i dunno what's the title of that manga so i search it on comments saying that manga was based of some thai bl story called "the red thread/until we meet again" im not really into watching drama so i just searching through mangago/any website with same title turns out the title was not that could someone perhaps know what title of this manga is?

hello! please help me search for this promo for a novel. I'll add the image in the comment.

Idk if anyone else is having this problem but, when you search up manga, does it not pop up option, or suggestions that you might be looking for anymore, is that only me. How do I fix it to give me suggestions again.
