1) After a few camping trips and failed attempts of trying to get the other to like their cooking, they end up resorted to making two meals. One intensely flavoured, the other... reasonably so.
2) Temujin will eventually make a dad joke in her presence, and it will completely go over her head. She'll take him absolutely serious, and it won't be until she's back in her yurt sleeping alone that she'll realise it was just a stupid fucking pun.
3) When they eventually grow more reluctantly affectionate of each other, it'll be the most tender or subtle of touches that truly communicate these feelings rather than voicing it out right. Rubbing horns, a soft caress, a longing stare and peaceful silence. It's a stark contrast to their aggressive, ahem, moments of conflict in the beginning.
1) Riki enjoys giving massages to Ryusei after training. It began mostly as an excuse to feel up his muscles, but became a quiet bonding activity for them to enjoy. Ryusei tried to learn some techniques from Riki, but more often than not, she demands his hands to be elsewhere.
2) When they begin to sleep in the same futon more regularly, Riki soon finds herself being trapped in Ryusei's arms every morning. Since there's no chance of waking him up usually, it's a sleepy wrestling match to free herself. Now and then, she'll accept her fate and get another hour of snooze snuggled to his chest. She eventually figures out that she can successfully bait and switch with a plushie.
1) They always crack open a cold one after a good old spar. Beer tastes better when you're battered and bruised.
2) They have a bad habit of waking each other up with their night terrors whenever they camp together. Cue the awkward stare, playing it off like it was no big deal, and rolling over to stare at the canvas sheet for the next few hours before sleep claims them again.
