I'm going to put all the warnings in here since I can't really tag properly like I do on ao3:

•This is a very angsty fic.
•Louis is very sad
•Past original male character/Louis Tomlinson
•Smut
•Past Harry Styles/Louis Tomlinson
•Happy Ending
•Friends to lovers
•Pining
•Slow burn/slow build
•Ex-friends with benefits
•Unrequited love
•Miscommunication
•Ot5 Friendship
•Bottom Louis/Top Harry
•Past relationships
•Blogger Louis
•Bisexual Harry
•Louis-centric
•Flatmates-AU

I believed that's all my tags for ao3 and I guess needed to explain before you even read it.
