After the Evil, Idiotic Fake Young Master Stole My Identity, I Went on a Rampage

In the group chat for first-year students, the student union president suddenly tagged me. “The richest man sure knows how to throw his weight around. He even donated a new swimming pool to the school. We have Little Master Li to thank for that.” I was stunned. When I checked in at the start of term, I'd complained to my dad that the school didn't even have a swimming pool. I hadn't expected him to take it to heart. I smiled and replied in the group chat, “My dad likes to keep a low profile. No need to thank him so much.” I didn't expect someone to jump in the moment I sent the message. “What nonsense are you talking about? I'm the real Little Master Li!” “And you're the student union president? If your eyesight's that bad, go see a doctor. Keep claiming my dad has another son, and I'll have you expelled!” The freshman group chat erupted, and the student union president kept apologizing. Confused, I asked if he'd got me mixed up with someone else. To my surprise, he immediately posted his household register and a family photo in the chat. “Look closely. Li Zhenhua has only one son: me. Could you be the illegitimate son my dad raised on the side?” Seeing that familiar face in the photo, I flew into a rage and immediately called my dad overseas. “So you've been keeping a mistress behind Mom's back! Just wait till you get home. You'll be kneeling on a washboard!”
