When Xie Chu kicked open the dilapidated wooden door, he just wanted to complete a perfunctory debt collection task and anger his father who had cut off his living expenses.
Inside the door was Ling Chu—a cold, sharp boy who looked like a sophisticated computer. His father ran away in debt, leaving behind a broken home and heavy debts. He survived with only a few part-time jobs and an extraordinary IQ. For him, emotions were redundant codes that were difficult to parse.
A wrong encounter forcibly binds two people who should be at odds with each other. The pink-haired, rebellious and rebellious young master of the Xie family, and the taciturn and prickly Ling Chu were forced to start living together.
Ling Chu witnessed Xie Chu hiding his inner scars with cynicism. From testing each other to relying on each other, they accidentally touched the only warmth in the cold reality.
"I'm hopeless. Do you want to go to hell and crawl back together?"
"Hell is fine, but you have to hold me."
Heartbeat is like fate, irresistible. However, a huge shadow has already fallen. The group's increasing pressure, the dark secrets hidden by their parents, and a carefully planned fatal boyfriend... They were forced to join forces to fight back against the unfair world.
This is a journey of mutual redemption in the ashes. They must use their own way to settle every crime and seek every ounce of justice until the embers rekindle and illuminate their future.
