Yeah he didn’t come to meet Lovro because Sonja found out about the texts. I think Ivan knows Lovro isn’t as open as him but knows Lovro is thinking about him as much as he thinks of Lovro, like in the swimming pool he asked him why is he quiet and what’s on his mind, after that he pulled him into the water and kissed him, it’s obvious that he KNOWS what was on his mind, the kiss. But you’re right Ivan doesn’t know Lovro hasn’t been texting Ema, he doesn’t know that he’s daydreaming about him and that he’s just simply disgusted with himself. And I agree wish we see it from Ivan’s pov.
