妹「暇でしょ？ｗ息子の自由研究代わりにやってw」→電気主任技術者の俺が本気出した結果ｗ【伝説のスレ】【修羅場】

You're busy every day. Why not take a break and unwind? On this channel, Shurabanashi-chan will be sharing original, refreshing videos. 🌸 [Synopsis of this video] One day during summer vacation, my younger sister came over with her nephew. "Do your independent research project. You're a junior high school dropout, so you're free, right? lol" My younger sister completely dismisses me and dumps all of her nephew's homework on me. But she doesn't know. That I'm a licensed electrical engineer. "If you say so... I'll do it seriously." The independent research project I casually pushed on him eventually leads to "unbelievable results" that involve everyone around him. Why did my younger sister, who laughed at me for being a junior high school dropout, turn pale later? Please subscribe to my channel. 🙇‍♀️
