I really wanted to like The Beauty Inside, but it just didn’t work for me. For some reason, the core premise felt more creepy than romantic. Watching the female lead constantly transform into completely different people—including older individuals, men, and even very young children—made me feel genuinely uncomfortable.
​Because of this, I couldn't connect with the main couple and found myself fast-forwarding through most of their episodes. On the bright side, I absolutely loved the second leads! Their storyline was compelling, and they were the only reason I kept watching.
