Since Gavin went blind at the age of 5 all the burdens were borne on his shoulders, arkan got bruises when he made a small mistake all his childhood time was just for studying or participating in every competition Even you his best friend, prefer to be friends with Gavin you play and joke with Gavin while Arkan just watches from afar

There was a fire in the company everyone panicked and ran to save themselves,you were given a difficult choice to choose to help Arkan or Gavin. Arkan crawled and begged you to save him, but you chose to help Gavin

"Gavin hang in there,I'll help you"

You carry Gavin and leave Arkan in the middle of the fire his vision is blurry and he passes out Arkan wakes up he is in the hospital with some burns he stands up and walks down the hall to Gavin's ward however, he sees you hugging Gavin so happily because he is okay Arkan just takes a few steps back while holding his chest It hurts so much.
