[Blurb pending revision. I may change it to the attacker being reborn, but everything else will stay the same!] After learning that his childhood friend Feng Yu had been switched at birth, Ming Qiao went to meet the legendary "real young master," Su Ze, out of curiosity.

The picture showed Feng Yu's arm wrapped up in bandages, with a lopsided bow on top. The caption read: Thanks, darling. You're the best. Su Ze had been dumped but still hadn't given up.
