Yue feels like he could die at any point because all his friends and loved ones died. Saeng/Ravin risked his life to save him and even killed for the first time someone, so he would ensure that Yue lives… This is going to make a shift in their relationship.
She boiled him water and then made the effort to chill it so he would have drinkable refreshing cold water. Obviously she has a crush on him. Boiling the water made sense, but doing the extra work of giving him chill water shows that she thinks of him as special.
And not 5 minutes after she gave it to him, he offered Saeng/Ravin to drink it. He completely discarded the feeling of this poor woman because I believe he didn't even see it as something she specially made for him. He doesn't see her feelings because his mind is occupied by those he is developing for Saeng/Ravin.

Poor Saeng/Ravin, he didn't think that he would be hit with the vision of a half-naked Yue when he was going to take his shower. He really couldn't stop staring at him, realizing at the same time how much he finds him attractive, while being unable to process it properly.
This episode was really here to show how Saeng/Ravin and Yue are being really aware of each other and realizing that something is blooming slowly. There is a feeling they can't quite explain.
They couldn't stop staring at each other as if they could find the answer about what they are feelings. It stirs something in them.
Every stares, every touches are a reminder that it's not just a comradeship between them. There is a "what if..." now.
But until they are sure about what they are feelings, they just won't do anything about it. Even that almost kiss remained only a missed opportunity for now.
