Somewhere Winter (2019)

Joon Sang moves to a new high school in search of his biological father. Yu Jin and Sang Hyuk are close childhood friends, although Sang Hyuk wants to be more than a friend, Yu Jin sees him as a brother. On a trip together with other high school mates, Oh Chelin, Jin Suk and Yong Kuk, Yu Jin is saved after an accident by Joon Sang. They become close and she opens up his cold heart. However, circumstances and fate dictate that their love will never be. He abruptly disappears from their lives.

Ten years later, the old High School buddies gather to celebrate Yu Jin and Sang Hyuk's soon-to-be wedding. Yu Jin, who was deeply in love with Joon Sang, still has a fire in her heart for him. But at the party, Oh Chelin's new boyfriend arrives, who appears the same as Joon Sang.

Both movies has kind of same concept. Two generation lovers met. The younger generation realized their parents were the lover before. Very romantic heartwarming movies. Totally worth watching. The main leads on both movies did a fantastic job and very beautiful couple

Look at the posters, they are the same! LOL these two movies gave such sentimental feelings.
I can say that both are very very very similar!!!
But they both got their own plots, personally Ii still liked Us and Them better, but both movies were good!
