Suterareta Yuusha no Eiyuutan - Story 2-Another 2: 『Yuji-san』

The poor Commandery Princess is down and out. Her father died when she was young, and her mother passed away not long ago. Her grandfather, the only one she can rely on, is now at death’s door from his illness. Faced with the merciless uncle, the greedy aunts, as well as cousins competing to present the model of the worst relatives, the Commandery Princess could do nothing but feel depressed in heart.

As a real young master of a wealthy family who was taken away by mistake, Chen Mo has never understood why it was him who was lost outside for seventeen years, and everyone still liked the fake young master Yang Shule, so he fought hard to fight, to grab, and to rob. In the end, his parents hated him, he was abandoned by his relatives and friends, and he died unexpectedly. So after rebirth, Chen Mo thought it over. Laughing makes you ten years younger, and going to bed early can help you live till old age. Not long after returning home, his biological parents asked him: “Chen Mo, do you think your brother… Can he still live with us now?” Chen Mo said sincerely: “As long as you are happy.” Aunts and uncles praised the fake young master during festivals. Chen Mo drank the wolfberry and red dates mixed soup and nodded repeatedly: “Yes, you have good taste.” The people around him openly and secretly compared the two of them, mocking him for not being worthy of the identity of a real young master of a wealthy family. Chen Mo slept soundly while soaking his feet in medicinal water: “Isn’t this a fact? Just keep talking about it, you can even go out on the streets with a loudspeaker.” Others: “…” Later, people found out that this real young master picked up by a wealthy family is best at three things. Eating, sleeping, and being gay. Not only is he gay, he also dumped the excellent student in his grade, who was the childhood sweetheart of the fake young master. Chen Mo felt extremely wronged. Xi Siyan, the cold-faced devil, didn’t like him in his previous life. How did these people came to think that he dumped him. “How about I explain it for you?” Chen Mo tried one day. The person leaning against the wall looked down at him and raised his eyebrows: “What do you want to explain?” “You, Xi Siyan, will have nothing to do with me, Chen Mo, in this life, the next life, and another next life.” The person in front of him kissed him with his hands in his pockets, and said coldly: “Now I do.” Chen Mo was shocked; Xi Siyan! You dog forced me !
