Love the drama. It has simple messages such as be good to family, there is room for one's improvement etc..The acting is so great matched with the understandable storyline made it easier to digest. Although second lead syndrome plays a big role in this drama pace, the main lead actor and actress really made journey through their character resulting in good character development. The OST? Simply menacing and good placement of SFX and music in the drama. This drama have a lot in common with 17 again movie from USA since it based on that movie. Love both those movie and drama ❤❤❤❤❤..
