[Webtoon Idea] The Spring that Reminded Me of You

I’ve already felt pain. Winter. The cold, freezing air that makes you want to let go.
But what happens when the gentle breeze of Spring comes?

Yuki, an 18 year old adult, has had enough emotional pain in his life. He lost his best friend when he was 10, his father left his family, his mother passed due to her sickness when he was 15, leaving him and his little sister by themselves. He puts on a mask to the people around him and his 10 year old sister. His cold past still haunts him, but what happens when it comes back for him?
