It is a "normal" day in Ikebukuro until Shizuo ends up seeing Izaya. They start to fight as usual, but all of a sudden Izaya freezes up and falls victim to one of Shizuo's attacks. Shizuo, feeling bad for the so called flea, takes him to Shinra's, and after a turn of events, Shizuo is stuck taking care of Izaya. What will happen when all of a sudden Shizuo is being kind(ish) to Izaya? And what is the feeling in Shizuo's chest whenever he thinks of the informant?
