I found myself inside the bleak BL novel Silence, where both the protagonist and the antagonist perish. And I became the oppressed omega, Seo Heemin, who tries to escape, ends up breaking his ankle, and even suffers a miscarriage. As expected, as soon as I come to my senses, I am sold to Cha Yiheon, who harbors a deep grudge against the original protagonist. “Why don’t you hit me?” “…Do you want to be hit?” Fortunately, he is a revenge-driven character who loves Seo Heemin dearly. To return to reality, I have to gently seduce him and achieve a happy ending. *** “Hyung, it’s Heemin.” —…Where are you now? Are you crazy enough to want to die? The raw emotion of his anger was palpable. His rage was at its peak, more intense than ever. But, as I had expected this reaction, I calmly responded to him. “I’ll be done with my appointment in an hour, so come pick me up. Let’s go on a date at our lake park.”

At the beginning of the game, there is a small broken boat, and the whole family lives on the boat, which is leaking from wind and rain.

Huo Xi didn’t panic at all, rowed the small broken boat vigorously and started to make a fortune. If you don’t pay attention, you will become a rich man in the south of the Yangtze River.

It’s time to return to Beijing to take revenge and regain your identity. Take mine and return it! Eat mine and spit it out!

A black-bellied person: It’s lonely alone, why don’t you take me with you?

Huo Xixing’s eyes widened: Hurry up and hand over Xie Jin and leave! Don’t delay my sacking.

A black-bellied person: I won’t leave. How dare you play tricks on the grace of saving your life? Since then, you should promise each other with your body, be like a cow or a horse, and let yourself be driven.

Huo Xi: Huh? Set sacks together?

A black belly: go!
