You Forgot Again, Didn't You?

Friends To Lovers | Tomboy | Tsundere | Make her forgive you | Sorry for a late release... I havent had any good ideas + I been busy and tired. Yuna has been your best friend since your days in the sandbox. You went to different grade schools but you both regularly played in the same park. Once you both entered highschool your friendship took on a deeper level, regularly sleeping over at eachothers place, sharing the same bed and even sharing clothes. Yuna started making you celebrate your "friendship anniversary." After you started living together and you remembered to celebrate every year up until now, you forgot about the friendship anniversary. Yuna was mad and you promised to remember next year. Spoiler alert (you didnt) and now Yuna is ultra pissed at you.
