At the start, it shows Gyu-hwa, Haesu and Jeongwu playing together and even mentions a cat they all took care of together but a chapter in the mid 20s shows Jeongwu meeting Haesu for the first time, freaking out over Haesu and Gyu-hwa meeting and then Gyu-hwa moving away. There doesn't seem to be any time for them to all play together and be friends.
