The main character (FL, so no shounen/seinen pls) saves the ML. Less of a one-off thing, and more like Nine in Beware the Villainess, or Li Wei in Rebirth Plan to Save Leader. Like, she saves his life or rescues him or supports him (physically, emotionally, etc) and so on. thanks!
I love that one! I took a break reading it tho, idk when I’m going to finish it, bc I saw a spoiler that Spoiler ML went to jail bc of his Cyber Crimes TM, and it was like, for a while? Maybe forever? Is it worth finishing, should I be scared?
It was not forever and yes it is worth finishing. I once saw a similar thread like yours asking for novels similar to Devil's Warmth and one of the recommendations was Rebirth Plan to Save Leader. Devil's Warmth and Rebirth Plan to Save Leader are probably the closest thing to each other. This one also fits your description but it's set in the past https://www.novelupdates.com/series/i-raised-a-sick-and-weak-prince/
