Death March kara Hajimaru Isekai Kyusoukyoku (WN) - Book 2 - 2-4. The Afternoon Date with Soldier-san

It was only after Su Yayan's death that she realized that she was a malicious cannon fodder female character who became a scapegoat in a Mary Sue story.

The “Dog Emperor” gets adopted by his fake “Favored Consort.” This story follows their story as they experiences all sorts of trials in the imperial harem and find true love.

The dog king will recover his human body.

This is not a legitimate harem drama novel – there will be love, there will be pampering.

Enormous silver platters, shocking melodramas, all part of the package.

Looking at his own concubines and imperial offspring from a doggy’s perspective:

Who used to be the sweet and gentle eloquent flower turns out to be a venus fly trap behind the scenes.

Who used to be the filial and courteous, intelligent and adorable imperial princes and princesses transform into demons in a flash.

The progression (of the story) overturns understandings and unmask countless illusions.

But by the protection of the gods, the dog emperor met a healing owner. Although the path is rough, the end is pleasant.

Gu Jin crossed into a novel as the supporting character and best friend of the main female lead, Cheng Xin.

Cheng Xin was frequently surrounded by men of status and quality. As Gu Jin was the female lead’s dearest friend, she doesn’t mind settling for the leftover meager soup if the female lead chose to eat the meat. The two sisters believed they’d enjoy this friendship for a lifetime.

But just as she was ready to latch firmly unto Cheng Xin’s golden thigh, she discovered the body she crossed into had memories of future events beyond the novel’s plot, finding out that her marriage would end in utter failure.

The female lead, Cheng Xin who often quarrelled with the male protagonist would head over to Shao Chong for comfort even though Shao Chong was married to Gu Jin. And after several incidences, Gu Jin advised Shao Chong to have a sense of propriety as her spouse but he told her not to think too much about it, claiming that he only maintained a pure friendship with Cheng Xin.

On the day Gu Jin was kidnapped, her good husband stayed by her cousin’s side and accompanied her to the hospital.

When Gu Jin transmigrated into this new world and learned of the truth, she did not wish to waste this new life as a supporting role for her cousin as the previous soul had done. She’d not live a life as a spectator in someone else’s love story. No. She would be the protagonist of her own romance in this new life.
