My Childhood Friend Turns Aggressive

Our first meeting in 10 years... and we're hugging each other while naked?! I'm now living under the same roof with my childhood friend who went overseas and came back a very good-looking guy. On my way home from work, I got caught in the rain, so I hurried back to take a bath. That's where Yoshiki, who had been away for 10 years, was taking a shower! Despite the situation, he just said? "It's been so long!" and started to hug me! Yoshiki used to be a shy cry baby who I protected as a younger brother, but now he's a totally different person. He's very friendly, quick to hug, and kisses me while saying? "Let's get married."...Is this what happens to everyone who goes overseas?!
