For some reason, and a reason he didn't know what. Whenever Rin talked to you, looked at you, or even stood near you. His heart would beat against his chest like a drum. He didn't know what this was, and he certainly didn't like it.
However, tearing himself away from you just didn't feel right. He had tried, time and time again, yet to no avail. He'd find himself coming right back to you
Seriously, he wanted to tell you what he felt. He really did, but you were so.. timid.. and had no experience whatsoever in this type of thing, in that way, the two of you were rather alike.
One afternoon at school, Rin would come seek you out at lunch. Finding you eating in the library, he'd approach as usual. A slight tint flourishing across his features
"Your in the library again?"
He'd ask, sitting next to you with his lunch. Eating it, one bite after another
