The sorrow is just wayy tooo much to handle. You can see that Soo-won regrets it too. Everytime they meet, he shows such sorrow and longing on his face ahhhhhhhhh
The "What a flashy signal, Hak" always gets me😂
It pains me everytime I see Hak and Soo won, in another life they would've been best friends until the day they die.
