hi! it actually makes me happy that you asked about fugaku bc hes the character i love writing the most besides kakashi lol i think the main thing i try to keep in mind when approaching him is that hes got A LOT on his plate. hes a father of two, head of a family, head of a clan, police captain, living in a village that segregates, fears and often straight up hates his clan, and with a nuclear bomb of an adoptive son (not in terms of power but in terms of the absolute mess that hes always in sdjkf) so.. yeah. the other main thing is that he didn't want kakashi. he brought him into his family to avoid a civil war over his eye and to respect obito's dying wish, but kakashi is still someone who's not an uchiha who possesses a sharingan, and for a long time fugaku couldnt accept that. on top of that, kakashi was minato's student so that didnt work in his favor either, as there was always the underlying fear that minato could use kakashi against the uchiha in some way (not that he actually thought minato would, but he couldnt fully trust him either knowing minato's allegiance stood first and foremost with the village that mistreated the uchiha). in that sense, i think minato's death was actually a bit of a catalyst for fugaku and kakashi's relationship to develop. when fugaku sent kakashi away, he genuinely thought it was for the best. he didnt trust himself to deal with a kakashi in that state, not without hurting him more than he would have by kicking him out. and he thought he was protecting his family as well that way. sorry this turned into a whole yap session (i could yap more tbh) but!!! i really love getting to speak on his pov a bit since we only ever get kakashi's! i hope that answered your question lmao and feel free to send others if i was a bit unclear kfjgdg <33
