At first glance, the older sister seems to be plain and has a quiet personality. She doesn't even wear contacts, and her outfit isn't exactly cute, so it's almost like she's avoiding men. Ordinarily, Shimiko-chan, who is not used to men like this, will not be able to take the next step even if a man invites her. However, I got a rumor that only girls with plain looks can easily talk to her without looking away from her because they are used to men. This time, I actually verified this rumor with my body!
