He Wants to Make His Childhood Sweetheart His Empress, So I Make Him Abdicate

Looking for Short, Tearjerker Stories Like the Ones in TikTok Ads

In the ad, the heroine is diagnosed with terminal liver cancer, or the male lead asks her how much longer she's going to keep pretending. Anyway, in the end, he sees her body and panics. She doesn't necessarily have to die, though. A happy ending is fine too. I just want to see how this kind of story ends.
