One trope I absolutely looooooove reading in Obikin fics is Anakin taking notice in his height difference with Obi-Wan, and enjoying it. Like even though he isn’t “that much taller” he still likes having moments in which he likes to take advantage of his height.
Like Obi-Wan being the perfect height for soft little neck kisses.
And for giving bear hugs, picking his poor, former master up and swinging him around like “loooook I’m strong enough to carry you around like it’s nothing” and Obi being like “yeah, yeah, yeah, I get it Ani, you like being tall and toned, now please put me down”.
It’s so frickin’ cute.
