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! The OST was diverse and delivered a retro vibe that fit the theme of the show which made it astounding. This show has even sparked my curiosity to learn sign language! Beautiful show nonetheless.
