suggest me the book where MMC is the writer or poet

Guys i need book rec where a famous grumpy writer is having issue (whatever that maybe, writer block or anything else and he abuses alcohol) finds his muse in younger FMC and falls in love with her. He just admires her from afar and begins writing ( poems, book or anything else- its has not be specific). -agegap -slowburn
-unrequited ( if available, if not then okay)
-Abuses alcohol -grumpy -not super steamy ( not at all is also fine) -if it is not unrequited then they should get together at the end of the chapters -I hate everyone but you kind off -MMC falls first
