Yin Kesheng is a person with low self-esteem and cowardice. He can only curl up in his own world until he meets Wen Haoyu, that boy who is like sunshine.
He stayed silently beside Wen Haoyu, feeling the only warmth. When they were together, Yin Kesheng thought it was a dream, and it would eventually wake up.
When Wen Haoyu's fiancée appeared and threatened him with Wen Haoyu's reputation, he knew it was time to wake up from the dream.
Finally, Yin Kesheng left. It was not until the end that he discovered that the love that penetrated the bone marrow was a pity to abandon, and he was obsessed with bones.
