Definitely a worth to watch! I am into K-drams for a long time but I stopped watching for a year fortunately this drama always pop up in ads and I get curious on it to the point that I've downloaded an app just to watch it and yeah! I am not regretting it! This drama made me laugh, cry, uwu, smile, and touches my heart. Now I'm back for being a k-drama fever. Well done, 18 Again!
