Machina Arcanis: Two Worlds Collided - Chapter 135. Arcana Institute

Reborn into her younger years, she's determined to rewrite her fate.This time, she'll earn her own fortune, buy that dream villa, outsmart every scheming character, and never hesitate to protect herself—even if it means hardening her heart.Her (blinking in disbelief):“Wait… does this mean I'm now on the same level as a rich tycoon?”Him (smirking):“Not quite. You're already standing on the tycoon's foot.”

Before rebirth, Xia Man had been wondering, when did Qu Zhen begin to hate her?

Was it when she foolishly followed behind her and constantly talked while eating? Or when she would always clumsily break the gifts she was given? So she started hating her?

Did she think such a person was not worthy of being her friend at all? Doesn’t deserve the sunshine?

Right! Sunshine or whatever, it can only be her Qu Zhen!

Xia Man always felt that the friendship between the two people was like Qu Zhen’s alms to herself, never equal.

Xia Man didn’t understand what Qu Zhen meant until she died.

“I thought I never missed it. Now I understand that I’ve never been right.”

Qu Zhen, in a sense, died by Xia Man’s hands, not from a zombie.

Qu Zhen, you could never have been right after doing something wrong. You should never fall in love with a person with a distorted personality.

After Xia Man was reborn, she only wanted one thing.

She wanted those who used her to hurt Qu Zhen to die rather than to live!

High-school student Koremitsu Akagi finds himself attending the funeral of Hikaru Mikado, who had died in an accident during Golden Week. He’s not sure why he’s there, as he only exchanged a few words with Hikaru at school. However, Hikaru doesn’t seem to be completely gone from the world, as he comes back as a ghost in order to fulfill a promise to Aoi Saotome, his fiancée. Since Koremitsu is the only one who can see him, he asks him to carry out his promise in his place.

Complying with his request, Koremitsu tries to fulfill Hikaru’s promises to the rest of his “girlfriends”, helping them overcome past misunderstandings and repair broken relationships.

Crossing across boundaries from a decade ago to now, a world that gives woman full respect and acknowledgement….

Don’t be fooled by her, because she was someone who would act obediently in front of a crowd but, stabs them in the back when necessary! Disguising as someone that would gain her trust and belief! That was why the Emperor of Xian started doting on her, allowing her to become absurdly daring to do whatever she liked. This made the Empress speechless to tears.
