Viewers might think that this episode is a filler and decide to skip, unfortunately it isn't. It was heavily implied early in the series that "love" may have something to do with our heroes' power source, and the bond formed through it is directly connected with their combat prowess. This kind of explains why there is a need for these slice of life moments, to balace things out with the action and suspense as they have far more significance to one another than previously anticipated. But then again, eveything escalates out of control in the end so it will be the test if anything comes out from all these. Nevertheless, next episode is going to be chaotic, let's see how it goes.
