I watched it because of Seo In Guk. Basically this is a story of a May-December love, office romance and family. I like it. I never thought that I would like Kdrama like King of Highschool. I discovered it through an ig account and it goes on. I love how they portrayed their characters well. The acting is superb — i know that SIG can pull any kind of character the PR would give him. It was nice, it makes you cry, laugh, frustrated, cry, and it's nice to be in love afterall. If you want something to watch that will make you laugh, then please watch King of Highschool.
