honestly except for the restaurant scene I never really considered anything else to be hints so it was kind of poorly built up for me.Same reason why I cared about the ship as well, I kinda gave a fukk about the main character. Mako got to do his dirtbaggery in season 2 but his character was hella limited without her which is why I'm glad that ended. Now in season 3 we saw the hints that they Korrasami could be a thing but folks kinda laughed it on/off but in season 4 with that restaurant scene, it definitely hit me with the " yall are really going to go down this road or are yall just going to keep messing with us."
If she were to end up single I was hoping for a time skip to see how things were in the future but this worked out even better...but a time skip would be nice as well.
when korra said let's go on a trip alone I was like cus I knew where it was headed.
for my own enjoyment I'm just gonna pretend they realize the relationship isn't gonna work out during the trip and break up
