I think sisters in Japan have a huge struggle with fighting their attraction to other sisters. I once asked a pioneer sister to date with me. I thought it was a done deal, but she shyly admitted that she wasn't very interested in guys and implied she was waiting for Jehovah to fix her in the new system.
Another time, I asked a sister out, but she said her future goal was to live with another sister and pioneer together up 'til armageddon.
Another time I became quite close to this family with two smoking hot daughters (both in their 20s). I was their English tutor. One night we had a lot to drink at their house. So they dress me up, put make-up and lipstick on my face, made me wear a straw hat and drove me to the nearest convenient store. While filming me in the parking lot, I went inside and bought something. The goal was to get the convenience store worker to shake my hand. The guy behind the counter was very disturbed by it all, but I ended up telling him all this was to impress a girl outside, so he shook my hand, patted my shoulder and said, "ganbatte! (good luck!)" with a wink.
Some version of fun, huh? The things we do for girls right?
Things were going good until the family packed up and moved to Australia where we got out of touch.
Ironically, years later, both sisters are still single and have zero interest in romance.
