He's such a gentleman and so adorable~! I find it hilarious when you can ask if "Why do you talk like a lady" though. XD I love their relationship IB and Garry have, surely after something like this nothing can stand in their way in the real world.
Have no fear, I believe he's supposed to be gay. Some of the things he say when you talk to him show a more feminine character (one of the comments Ib ask Garry is why he sounds like a lady and he nerviously responds something like, "no no, I just wanna sound more...gentle). The Japanesse version text reveals more of how he talks.
oh my god, do you know how long it took me to find this picture? D: Someone posted it on Tumblr without adding a proper source, and I've been searching for at least 10 minutes before I finally found your DA page.
