Hallo! The person who posted the comment will most likely not be able to send any replies since that person needs an account but I'll offer you the spoilers, since I too have already seen the final chapter. The ending wasn't sad don't worry, it's a happy ending, the way how the author created it was both very romantic and heartwarming. But tearjerking since the journey has officialy ended in the Korea version. *spoilers*
The first snowfall of the season happened in Korea, the two decided to go out in the middle of the snowfall, because if you didn't know, in south or north Korea the first snowfall of every season or year has a good meaning to it. When you go out in the first snowfall with the person you love, "true love will blossom" and your wishes will "come true", it's like the two are planning to make a commitment for the future for their relationship to grow even better than it already is, so they were excited and very happy. To explain more, the "smile" thing that the person was referring to was about Dojin, and the person was right about his smile, and might even be one of the best smiles I've ever seen in the entire series or BL, cause the expression on him was so full of joy and longing, that made my heartache, if a smile could heal then his smile could have healed millions. Plus the final messages while it was snowing was very touching and meaningful. Sorry that it was long btw (・_・;)
Guys....sad to say that the series has truly come to an end in the raws. And holy shit the chapter hit me so damn hard and might even be one of the most beautiful and memorable endings I've ever seen, author Pengki did outstandingly. Dojin's final beautiful smile made my heart ache so much HIS FINAL SMILE GOT ME SO BREATHELESS DAMMIT LIKE THE EXPERESSION IN HIS EYES AND EVERYTHING MADE IT SO BEAUTIFUL!!!! The side couples are both doing fine in their relationship, and what struck me the most is how the journey of the main couple have ended like, the hardships that they've experienced when they haven't met each other yet to that type of ending. Am hella weeping badly here, and call me an overreacting weeb here, idc, it's how I felt while reading it. So yeah, can't wait to cry again when I read the English translated version of it...and I can't wait for a new project from author pengki ofc.
