A story about a girl who has a grandmother that has Alzheimer's disease who loves to tell her stories about her long lost love. Mei (original character) started to feel this Déjà Vu thing when she met this boy named Kim Tae Hyung who terribly looked like TAEJUNG (Grandma's long lost love). And then it turns out that the reason she's experiencing this phenomenon is because of her grandmother's stories that seemed to be happening to her too. Ama (grandmother) and Taejung didn't had their happy ending. Will Mei and Taehyung too? or maybe it's destined for them to give this love a second chance.

Maybe yes or maybe no

Maybe it's maybe, neither I don't know

She'll meet someone better

Someone who wants to prove her the word forever

Sure he'll give her a better ever after.

That it could make her say no to what is fated after all.

One things for sure, they could all just go with the flow

Cause in the first place, I swear it's Deja Vu.

Déjà vu, from French, literally "already seen", is the phenomenon of having the strong sensation that an event or experience currently being experienced has been experienced in the past, whether it has actually happened or not. -Wikipedia
