So what actually happens?
There is a guy named Ha Eun Gyeol, he's passionate about music but he is currently the trophy son to his deaf parents and the only person who can communicate with the outer world in his family. And boy got a deaf brother too (Ha eun ho) who does taekwondo... So dude gotta be responsible for all of them but his guitar keeps calling him and he's unsure if he should pursue music or not... One night magical shit happens and he lands in 1995 where his parents are now his age and he is now going to play cupid for his future parents as younger version of his father (Ha Yi Chan) is a lively youngster who is in a band, is chasing a popular girl, has no interest in studies or Eun Gyeol's future mother (Cheong Ah)

Twinkling watermelon is another sunshine kinda, wholesome, cute cum melodramatic sometimes yet funny and enjoyable youth drama that I would recommend to anyone who enjoys this genre.

This show has a lot of music, dramatic comedy (often overdramatic with exaggerated expressions but trust me it will make you smile), two cute couples and a bunch of high schoolers who would apparently form a band and great friendships (usual to such youth dramas).

What I loved the most in this drama is Yoon Cheong Ah, the bunny girl who is literally the word "cute". A deaf girl who has not received much warmth growing up but she isn't all weak and tries to protect herself in whatever ways possible. I love how they chose the right actress Shin Eun Soo for this role because her smile is honestly all pretty and as worthy as Eun Gyeol talks about in some scenes.

Younger Ha Yi Chan acted by Choi Hyun Wook was again a bonus because we know he's great at portraying this funky outgoing guy vibe. Chemistry of Ha Yi chan and Cheong Ah was also so mushy and natural that made me root for them all along... Ryeom and Seol in ah also did a convincing job at their roles... haven't seen Ryeom before but he was good at acting all those frustrating scenes when he had to face the mess of his time travel.

Also I don't think I need to mention this but you gotta love the father-son duo, be it 2023 or 1995, you'll love how they fight, bicker, protect or kick each other or have emotional conversations. They're simply adorable.

A noteworthy character here is Yi Chan's grandmother acted by Go Doo Shim. Loved her positive presence throughout the show... somehow this show is such a comfort watch thing and quite entertaining if you end up liking the characters. I watched it as it aired so I actually become reluctant towards the end that like "is it really ending tomorrow? I'll miss them"

You'll get the suspense of "if Ha Eun Gyeol can make things right" as a bonus. The ending might have raised questions but most of the major questions were answered in micro details while some mysteries like the time travel link, the shop Viva Music are better left unanswered (because I don't think a satisfying backstory or explanation can be built for that) so its better being left like that.
