Not sure why good is in quotation marks but here are a few that are good to me (If this is you asking for smutty recs, I apologize cause these are all sfw...)
White Blood - A lot of tension and the wait for them to get together is pretty long. It's also very plot heavy and the romance is a sub plot!
A Way to Protect the Loveable You - The mutual pining is what gets me every time. The friends the fl makes along the way also makes you cry a little.
I Stole the Number One Ranker's Soul - The beginning is great with the two of them and their bond. The end is a bit rushed but the one scene where they hug still gives me butterflies.
