i've done it guys, here's a thread of all the unscripted Why R U ZaintSee scenes (as far as i know)
Warning : lots and lots of kisses

The infamous ep8 adam's apple kiss

not 100% confirmed but the little peck while packing at ep09

so nvm this one is indeed totally unscripted

The mroning kiss from Zee is also rumoured to be unscripted Ep10

Zee holding saint up was also unscripted, he did it all by himself

The little kiss and peck on the nose from ep09

Also not confirmed but many think this one is unscripted too - Ep10

Them playing after brushing their teeth was totally unscripted - Ep10
