I've Got a Green Cloud Hanging Over My Head

Mr. Wang had been married for seven years when he hit the seven-year itch.

Just then, he discovered someone had cuckolded him.

Mr. Wang: "Which bastard dares to cuckold me?"

*

He finally tracked down the bastard, only to get into a car accident.

Mr. Wang: "MMP."

*

He opened his eyes and found himself transmigrated back to six months earlier.

Mr. Wang decided he would nip every threat to his marriage in the bud by moving in next door to his wife.

"Hello, I'm your husband's half-brother on his father's side."

*

When his wife was unhappy, he cheered her up. When she had no money, he handed her a bank card. When she was lonely, bored, and cold, he showed up to warm her up.

Then...

His wife: "I've decided. I'm going to divorce my husband."

Mr. Wang: "…????"
