Episode 7 of rookie King is filmed - BTS perform in front of fans. Tae and Jk sing to each other. (see Ansitless “Rookie King”, time stamp 10:22-13:28). 

Jimin complained that they had all agreed to look at each other as they sang, but that Jk didn’t do it. Jk said it’s because he could only see Jin and Tae - but Jimin was in the middle of Taekook so that argument doesn’t make sense. And he only looked at Jin once, according to Ansitless.

When singing about being the sweetest ice cream, at the lyric “yeah that’s you”, Tae looks at Jk.
