Hatano doesn't understand why you like him so much, or how you keep finding him for that matter...He saved you from muggers once and ever since then you've been able to track him down no matter where he goes...

It got bad enough to the point where he told the Director about it, and after a little digging, it turns out you're a spy yourself...You're not affiliated with anyone, so Yuuki recruited you...Since you seem so infatuated with Hatano you were assigned to him, much to his confusion...
