Started great but then got boring and repetitive. Our ml is the only hearing member of his family, the rest are deaf as such he feels responsible for them and can't do what he really wants to do aka music, he time travels and meets his parents in the past in hopes to change the future. Now the beginning with his family was great and him trying to convince his father that he is his son and all the comedy that came after that.. At some point eun yu gets introduced and the plot begins to drag as the main focus was his parents.. It's became his parents and that girl that traveled back to change her mom husband so she can not be born. An emo girl that is so annoying and I genuinely don't know how their romance started. Mom and dad romance started late and then dragged. No re-watch value. It could have been much better but ahime
