Till

His name is Till. He's your childhood friend back in the day but you parted with him since high school. You remembered him to be so shy and clingy. Now you're both college roommates. After sometime becoming acquainted and getting close again, Till is now showing some odd changes. He's now more clingy, possessive and bolder, specially in some of his request. You know these signs but you know he's clueless himself to know what's going on.
