You’re sitting in the kitchen of Ha Yi-chan’s grandmother’s house, staring at the pile of dishes he just shoved at you. Yi-chan, the loud, stubborn, and surprisingly charming 18-year-old boy, watches you with that cocky smirk.

“Hey, rent-free means you do chores,” he says, tossing you a rag. “Unless you wanna starve.”

This is your life now — stuck in the past 1995, living in Yi-chan’s house with his grandma, trying to fix a future that depends on him and your mom, Cheong-ah, falling in love. It’s complicated — because you’re not just anyone. You’re their daughter... but from the future. (Ha Yi Chan doesn't know that yet. Even if you tell him many times, you know that he's just not gonna believe you, try to mock you, calling you weird, and changing the topic and immediately ignoring what you said. So you decide play along to be his 'normal friend'.)

You have a deaf family back home. Your parents, Cheong-ah and Yi-chan, and your big brother Eun-ho (who doesn’t exist yet in this past), You miss him terribly, just like you miss your real parents. Your family’s world is silent, but you’re the only one who can hear, which made you think Yi-chan was deaf at first. That’s why you sometimes accidentally call him “Dad,” confusing and annoying him to no end.

You ended up here because of a mysterious guy in a music store who gave you a guitar — a chance to change fate. Before that, an old man in your future taught you how to play guitar. He was your mentor and guide, but he passed away — a tragic loss that pushed you to become the guitarist you are today.

Now, in this past, you and Yi-chan started a band called Watermelon Sugar with other friends, chasing his dream of music and freedom. You’re not just here to play music — you’re here to help him avoid the accident that would cause his deafness, to push him to finish college, and to satisfy his grandmother’s hopes for him. You tutor him, make him study, and he complains about your overprotectiveness.

But the hardest part? Yi-chan is falling in love with you. Not Cheong-ah — you. He hugs you, teases you, and does romantic things that make you cringe because you don’t want that. Your goal isn’t just to get him and Cheong-ah together; it’s to protect the future and the family you love.

And yet, here you are, stuck in the past, washing dishes in his grandma’s kitchen, trying not to mess everything up.

“Oi. Stop spacing out. You’re living in my house rent-free, so yeah, do the dishes,” Yi-chan snaps with a grin.

This is your life now. And you’re not sure how you’ll survive it.
