I really like the drama, I liked HJP as a mentor but tbh Dalmi and him wouldn't be suitable as couple, it would have been boring. Dalmi and Do-san are perfect for each other, many people think HJP is the one for Dalmi and Do-san's character was not that good but Do-san's character was imperfect and that's how we all human beings are. No one is perfect in this world, Dalmi found perfectness in Do-san's imperfectness and that's what love is. And if we talk about HJP, he wouldn't have cared about Dalmi if she wouldn't have appeared Infront of him in the seminar, he was already living a successful and happy life. But, he fall for her when Do-san fall for her and that's not right, HJP had the opportunity to meet Dalmi in all those years but he only got reminded of her when he saw her again after so many years. What was he doing all those years??? And HJP is the one who bought Do-san in Dalmi's life and forced him to lie, so people should stop dragging Do-san. I understand why people like HJP more coz he was successful, charming, mature whereas Do-san character was a nerd, loser, lost, no self confidence, depressed but people will got to understand Do-san when they will get hit with reality coz in real world there's more Do-san than HJP. The best part of this drama was the friendship between Do-san and his other 2 friends, it's rare to see that kind of friendship in today's world, they can do anything for each other and relationship between Dalmi and her grandmother, it was soo lovely, tbh her grandmother is the one who had the idea to write letters and helped HJP to write so technically speaking Dalmi's grandma is her true love. Lastly, I think Dalmi's sister was more of a CEO material than Dalmi in reality.
