As we Collide ; BeomJun/YeonGyu

"Once a heart breaks, it will never be repaired." that is the mindset of Choi Beomgyu whose heart had been broken due to his past lover cheating on him.
As he left, he accidentally bumped into someone who gave him such comfort and realization. He wanted to once again meet and collide with that person.

As he continues to study, he also finds the person who gave him such care and words. Until he met Choi Yeonjun, a senior who had the same personality as the person who Beomgyu bumped into. But Beomgyu is still thinking if is he really the one?

What would be the fate of the two? What obstacles and challenges are there to face? Are they going to be the one for each other?
