In Shen Huaiqing's life so far, no one has loved him. He doesn't know how to love himself, nor can he love others.
The only way he can think of to express love is to keep He Zhen by his side forever, until he can't keep it anymore.
"I work hard to express my love, just for your occasional tenderness on a whim. Just like Pavlov's dog, as long as there is a little sweetness, I am willing to do it."
Purpose: Love others first, love yourself first
