When Lu Shiyu rushed into the boxing gym, he saw Gu Yu'an covered in injuries.
He thought Gu Yu'an was bullied and went crazy on the spot.
It turned out that the coach who hit Gu Yuan was the boyfriend of his teammate.
What's even more outrageous is——
Gu Yuan practiced boxing without telling him because he wanted to "become stronger so that he could protect his younger brother."
Lu Shiyu practiced boxing because of the same thing.
Both of them wanted to protect each other, but no one said anything.
(Gong and Shou are not related, it's just a catchphrase for young puppies.)
Intent: A true lover should not have one party protecting the other, nor one party accommodating the other, but two people working together to face the wind and rain outside together.
