18 Again One of my favorite KDrama. It's all about a guy on his late 30's who wished to go back on his highschool days and fix his life. I learned a lot of lessons while watching this drama like, whatever your decisions in life, you must not regret it. You must accept all the consequences of your decisions whether good or bad. If it's bad, the important thing is you learned from your mistakes. Nothing is easy in this world. Be grateful- You might desire what others have but others might want what you think does not matter in your life.😊
