I remember reading this story several times but I cant find it now, able to help me?

It's a michaeng fics...

I rmb it start with Chaeyoung waking up late from fetching Mina from the airport

They were ex

Chaeyoung has anxiety(?)

Mina was back for 2yeon wedding

On a specific day of the month, chaeyoung will lock herself in a room that is covered in cushion as she will lose control

I remember near the end they found out Mina was actually engaged or something

Anyone can send me the link?
