Keith is the one who is more openly in love with hunk (ie look at their faces during the Klunk Hug™), hunk is more shy about it, till the weblum episode, where hunk starts being more open and teasing Keith.
omg that is so CUTE ;A; And I can totally see it happening :’D Keith wouldn’t say anything though - I think he wouldn’t feel confident enough to confess because Hunk is perfect so why would he want Keith who is a mess of issues and has a temper problem? It gets even more awkward for him once his galra heritage is discovered, Allura is angry with him, and the rest of the team doesn’t quite know what to do with the new information so Keith is Sad™. Hunk notices, of course he does, and when he sees that nobody is doing anything to reassure Keith that nothing’s wrong, he takes matters into his own hands. Cue the weblum episode and the good natured teasing :’D They confess no much longer after that… or, more like Keith blurts it out in the middle of helping Hunk with the dishes or some equally menial task and Hunk is surprised but utterly delighted, and says that he loves Keith, too. Then they are both grinning like idiots, looking at each other and blushing madly, fidgeting with hands full of alien soap (dishes completely forgotten) for like, two entire tics until Hunk opens his arms and Keith all but flies into them for the Best Hug in the Entire Universe.
