After entering college, I met a girl in a club and finally got to date her. While I was happily playing with my phone, my sister suddenly popped out saying, "Brother! You're not secretly getting a girlfriend, are you?" For some reason, she's infatuated with me and was full of jealousy. Upon learning about my girlfriend, she declared, "I'm going to drain you before your date so you can't have sex with her!" As a result, my morning wood gets emptied every day.

I actually watched this work, and regardless of whether such a thing is possible in reality, the story development is incredibly entertaining. The sister Niko-chan's character is unbearably cute, especially her upward glances and the tone of her voice, which fit the role perfectly and made my heart race. Her jealousy feels genuine, fully bringing out the charm of the sister character. The acting is natural, and the emotional ups and downs are conveyed effectively.

Overall, it's a comedic-style story woven from the sister's one-sided love and the brother's confusion, leaving a lasting impression after viewing. Fans should definitely check this one out.
