There are various moments when a man falls for a woman, and one of them might be accidentally catching the scent of her hair. What? You don't think so? Maybe you've just never truly experienced a woman's hair scent. If you're curious, you might encounter such scents at soaplands or brothels. Though I've never personally been to such places, so I can't say for sure. But scents really do vary widely—citrus, floral, soapy, shampoo, sweat, scalp odor, even raw human smells. If there's a girl you think you might like, maybe your soulmate, someone you'd want to date and marry, try smelling her hair. That scent could drastically shape your future together. Even if you already feel attracted, mutual feelings don't guarantee compatibility. Couples who start out in love sometimes grow apart as time passes, eventually breaking up. But sniffing her hair beforehand might help avoid such disasters. Listen carefully: if her hair scent strongly appeals to you, go ahead and date her. It'll definitely work out. But if the scent is questionable, you'd better avoid dating her—because it absolutely won't work. Scent is a crucial factor in determining compatibility. You're all adults now; you don't have time to waste on relationships that lead nowhere. If you're going to date, you probably want it to lead to marriage. Once you start cohabiting or get married, you'll constantly encounter each other's scents—intentionally or by accident. That scent can calm your mind or bring small moments of happiness. But if the scent is unpleasant, it might make you irritable, emotionally drained, or bring minor miseries. That's why scent is so important. That said, hair scent doesn't really matter in this video. Sorry. If anything, maybe the protagonist "I" and lead actress Shiori Kuraki had terrible scent compatibility. I heard they broke up after a fight years ago—perhaps they were just physically repulsed by each other's smell. Not sure, though. They were once close enough to drunkenly film outrageous gonzo sex tapes together, so how did it come to this? Probably because they never checked their scent compatibility before dating. Or rather, they likely got together casually, without much thought. Maybe they dated back in college. College relationships are often like that. I once dated someone out of sheer momentum and got dumped after a month. Looking back, I never checked our scent compatibility. Big regret. Be careful, everyone. In this video, the woman puts the man through hell—but someday, she might end up suffering just as badly.
