Falling in Love with You Is My Greatest Happiness

An illness caused her to lose her health, but she gained love. When he saw her suffering from illness, he forced a smile; in order not to worry his family and friends, he hid in a corner and cried alone. Unconsciously, he slowly began to get closer to her and fell in love with her. In the end, she failed to defeat death and passed away at the age of 24, and he could only cry sadly, and he was alone from then on. When she opened her eyes again, she changed her body and identity, lost her memory, and was reborn. When they meet again, will they recognize each other? Can we still stay together until old age?
