One Piece: Supreme Check-In System - Chapter 13: Check-In Amazon Lily

Ace Carter Greyson, her husband of five long years forcefully divorced her on the night of their fifth wedding anniversary. Reason? Simply because she can't bear him a male heir.

Phoenix begged him to stay but his decision was firm and unbendable so she finally let him go. Her life was even more shattered after she discovered his long time affair with his secretary, and now, the mistress was pregnant. Just months after their divorce he married the impregnated secretary.

Phoenix's world suddenly turns upside down when she discovers she's four months pregnant.

Pet shop owner Tang Wan was accidentally reborn into an interstellar world. When he opened his eyes, he found himself automatically married to a vegetable via the StarNetwork. A social status worth ten billion yuan; but with an unconscious husband, he was unable to withdraw any money. Tang Wan held the empty position of the First Gentleman, but was, in fact, a poor man.

She, a renowned assassin of the 21st century, actually crossed over to become Su Manor’s most useless good-for-nothing Fourth Miss.

He, Jin Empire’s imperial highness, was an emotionless overbearing demonic tyrant with unrivaled talent.

Everyone knew that she was idiotic and good-for-nothing and bullied her as they pleased. But only he, the overbearing tyrant with the discerning eye, wouldn’t let go of her even if his life depended on it.

For the time being, let’s just see how the stubborn versus stubborn clash and play out in this good show of the chaser and the chased.
