Useless fellow evolving
We see how Joon-oh who seemed to be such a jerk in Seoul and useless on the island evolved to be the leader of the pack.
In the beginning, he finished all the remaining food supplies on the island without thinking and pushed Bong-hee to the front line in the face of danger (he delegated all survival matters to Bong-hee; he hid behind Bong-hee when Yeol came out of the bushes in the dark; he playacted when retrieving the suitcases from the sea).
Then during later episodes, he asked Bong-hee not to put other people before her own welfare and he went against all odds to save Bong-hee and So-hee when they were stranded on opposite island.
And his developing relationship with Bong-hee is so hilarious and endearing to watch <3
