Best k drama ever.. i dont know why every one is cursing nam dosan but i personally like the dosan character. I can feel his shyness, uncomfortable yet willing to keep dal mi on his side. Pyeong never gave effort for dalmi in past 15 years but dosan went to help dalmi as soon as he read the letters. Dosan never wanted to lie to dal mi,he always wanted to tell the truth but pyeong and haimoni never let him.
Overall i am quite happy that its dalmi and dosan in the end.
