I think he cares for him. Arima is often seen as this emotionsless killing machine but as seen in the TG jack manga he too had thoughts about living a normal school life and i think now in :re Haise gives him the chance to have a "normal" family life. Basically he's enjoying their "family" as much as Haise.

Besides that, there was this plot point of Arima never writing a testament since he didn't have anyone close to him. This is obviously going to happen again in future chapters of :re but this time with him writing something to Haise.
