I loved Zain in KY2 but it seems his acting skills have disintegrated along with the rest of the cast's since he started TI. However, I think he should continue playing the role because it's obvious that Kunj will eventually die and Yuvi will end up marrying Twinkle, which will start the next chapter of TI. For now, I am enjoying TI as is since Kunj-Twinkle's love story is panning out excellently, and Yuvi is doing a good job of being blinded by his mother's revenge mission yet still feeling like like he loves Twinkle/ she belongs to him. Stick it out Yuvi.
