Maou-sama no Machizukuri! ~Saikyou no Danjon wa Kindai Toshi~ - Volume 10 Chapter 15

To treat her sick brother, she was forced to marry him in place of her cousin, who was disfigured and paralyzed. At first, their relationship was purely transactional, with neither caring much for the other. But after going through a lot together, they fell in love with each other. He doted on her deeply.She was considered an ordinary person by the world, but it was later discovered that she had multiple identities - a mysterious underground boxing champion, a highly-skilled doctor, and a mysterious and renowned composer... He also realized that their fates had been intertwined long before they met.

After transmigrating into a beast world, Rong Mingshi discovered that the people of this world experienced widespread mania. For example, when their emotions were abnormally agitated, they would become destructive beasts. If their emotions were abnormally low, they would shrink into their young beast form.

One morning, after being bound to the system, MC started his routine of always being captured/ attacked by the ML.

It doesn’t matter if he transmigrated into the ML’s little brother (TN: Here I think brother disciple) or master or opponent, but in the end he is still forcibly taken by the ML.

After transmigrating to many worlds:

MC: Come out system!!! The heck?! Why do these MLs not love their female goddesses, but insist on doing it with me! Aaaaahh!!!

System: …. __(:3」∠)_ Don’t ask me, I also don’t know.
