I recommend the short story " Lock Your Heart with Iron Chains ". When the male and female lead first met, he was drugged and the female lead lost her first kiss that day. The third time they met, the two of them announced their relationship. On the second day, the male lead suddenly disappeared. The female lead took every step carefully and planned for the male lead to fall in love with her and not be able to leave her. In the end, she suddenly disappeared. The male lead used an iron chain to lock the female lead at first, and then the two of them started a tangled love story. I hope you like my recommendation.
