She Took the Four Seasons

Lin Suihan had a crush on He Xingzhou, and he married her to repay a favor to her brother Lin Suilin (who saved his life). However, over three years of marriage, Lin Suihan never felt a trace of love from He Xingzhou, living like a widow. She gradually realized that the only person He Xingzhou truly loved was his "white moonlight" Xia Qingchu. To avoid making He Xingzhou break his vow to take care of her for life, Lin Suihan decided to fake her death—leaving He Xingzhou to pursue her own dreams. But when He Xingzhou found out she was gone, he suddenly realized he could no longer live without her.
