This is a failure as a time travel drama since its ending has loopholes galore but as a family drama full of heart, this is one of the best. It doesn't have any major mind boggling concepts. You can almost predict the storyline but with cast's solid acting, their on point facial expressions, the simple story was really brought to life.

The main character, Ha Eun Gyeol, is kind, smart and handsome, the perfect son any parent would want to have. As a child of Deaf adults (CODA) with an older brother who was also Deaf, he always felt some guilt for being the only hearing member of the family. He tries to excel in studying so that people wouldn't say that his parents didn't raise him well because they were differently abled. But because of this, he began to feel like he was a trophy. It was only when he time travelled to the past that he was finally able to understand the struggles his parents had in their own youth.

When the MC returned to the future in the end, a lot of logical questions remained with me. Because I mostly enjoyed his journey and I kind of expected the changed future because of his interventions in the past, I chose to let them go and accept the drama logic as is. Everyone received their just ending so I'm good.

My main takeaway from this drama is Viva la vida, long live life. No one can live your life you. Life, like a watermelon, may have many seeds/struggles but it doesn't take away the sweetness that you can experience. Enjoy it, let it twinkle, but always choose to be kind when you can.
