A Mikhaiah Fake Dating AU. Everybody loves Matty Lim... well everyone, except Thea Arceta. Matty's the charming ex of Thea's younger sister, still oddly close to the family and always overstaying her welcome. A known troublemaker with a flair for chaos and flirtation, Matty has a way of getting under Thea's skin... and maybe a little too close to her heart. But when an unexpected twist of fate forces them into a fake dating arrangement, lines blur, sparks fly, and Thea begins to question what's real and what's just for show.
