Just dropping this novel recommendation here if y'all want something similar! It basically have some essence of it. Enemies to lover workmates, more mature(?) and experienced ML, good dynamics between the couple, and communication!!
Note/spoiler: Omegaverse/ABO and age gap

Ngl I'm loving the ML's white moonlight for our MC more in this arc than the ML himself lmao
ML is kind of a trash in this arc, man.
