"Twinkling Watermelon" started as a time-filler, but it ended up tugging at my heart. Viva teaching Eun Yul guitar was sweet, and the drama between the father and son had me on edge. The "Master" twist and the 19s lifestyle kept things interesting. Ha Yi Chan's romantic story was a highlight.

But, man, the feels hit hard when Eun Yul couldn't dodge the accident, and Yi Chan lost his hearing. Why didn't they spill the tea on Choi Se Keoung and her dad's story? Yoon Cheung Ah's happy ending was a win, but I needed more deets in the finale. Overall, emotional ride, but give me a fuller ending, please!
