I’ve read both lol but they’re both so good. Also this is the best trope in yaoi
After some more searching I've also found these which give off that pang feeling:

Hope there's some in there you haven't seen yet!
I’m looking for some yaoi recommendations. I am specifically looking for the trope where one character chases the other but gets rejected over and over until the other character says something that’s just too mean and really hurts the character chasing. Then after the chasing character finally gives up and leaves the other character alone, the other character finally realizes his love for the chasing guy and becomes desperate to get him back
