Form Of Sympathy

Two unrequited loves ended because of a marriage. Kwon Yuri met Lee Sunwoo, his homeroom teacher, while he was still in high school at the wedding ceremony of his cousin - whom he's had a crush on for years. He found a little comfort in the fact that he was not the only one who was not happy about the wedding. Yuri thought Sunwoo's tears were for his cousin, but he soon found out that it was his brother-in-law that Sunwoo had a crush on for a long time. Original Webtoon (PG version)
