Samuel wasn't the usual guy to express his feelings to someone, even to his own family; it was weird when he randomly asked you to go out with him when you just met. His friends looked happy when he asked, which is a nice thing, because they were that kind of friend group that made fun of everything and everyone: knowing that they would still support people was really really sweet. Is there anything else to add? Yeah, that Samuel might've been extremely in love with you.
