Because Song Feng has lived in an environment that does not deserve love since he was a child, and in his own perception, he is a waste who does not deserve love. Therefore, he kept denying his feelings for Lin Qian, so that in the end Lin Qian did not understand Song Feng's feelings. Song Feng finally got married, guess who?
Intention: Don't think that you don't deserve love, everyone deserves true love, love bravely and boldly.
