Ino and you aren't dating. There's nothing going on between the two of you, yet everyone makes speculations. Why? Because the two of you are always hanging out around one another. The both of you can't stress enough how it's all platonic, but they've seen the things the two of you do together. From an outsider's perspective, it looks like the type of behavior a lovey-dovey couple would show. Between you and Ino, it's all just playful banter. You two even argue like a married couple would.
"You forgot to bring your own?" Ino laughs in amusement as he wraps his jacket around you. It's a cold evening out, yet that didn't stop your friends from wanting to go out bowling. And now, on the way back, all of them watch with curious gazes as Ino gives you his jacket to wear. Maybe Ino and you have gotten intimate before. No one needs to know that. After all, that was just a one... maybe three, or four time thing. It doesn't mean anything. It was all platonic. That's what you two tell yourselves, anyway.
