I guess he was checking to see if Maa-kun had any feeling for fujiwara. Thing is Ryouu or w.e is forging his own path. He wants to be your friend and husband and hee figures he can be a far better friend if he shares similar interests and does similar or the same things. Most people when they do it, do it in an annoying way, but this guy ain't desperately clinging to her like what you usually see. Can't hate him for it
