Essentially a perfect show. The plot was unique and unpredictable. I loved the origin story between Yi-chan and Chung-ah. Watching how their first interaction blossoms into a romance is heartwarming. The relationship between Eun-gyeol and On Eun-yoo is entertaining, and their chemistry was on point. There were two character dynamics that stood out to me. One being between Eun-gyeol and Chung-ah, they shared many scenes that were impactful but there was one powerful scene in particular that brought me to tears. The second being between Yi-chan and his grandmother who had such a loveable relationship, and there was one scene specifically that had me crying. Chung-ah was undoubtedly my favourite character in the show as she was absolutely flawless and played her role perfectly! This show has even sparked my curiosity to learn sign language! Beautiful show nonetheless.
