@lovestar Just my thoughts... Hope they help.
I think the confusion will dissipate once more subbed eps are out but one thing is, it's hard to pinpoint time in this drama because it seems time speeds up and slows down often. There is a decent amount of time that transpires between his breakup with Ning and his full blown pursuit of Ju. It doesn't actually happen over night. Though I will say, Suea isn't one to dwell. Ning hurt him and he moved on, not necessarily to Ju (though she helped) but with life. That's kinda it and one of the great things about him as a character.
And in ep2, he definitely knew it was Ju. He was either awake or half awake. When I first saw it, I knew he was awake, so I didn't know what to think either, not because I thought he was confused but because I knew he wasn't. Hwr, we also know he doesn't have "those" type of feelings for her (yet). Plus, Suea comes across as a pretty simple guy, so if he likes a girl, she's all he sees. He doesn't entertain any other girls romantically. Therefore, I think the issue is that part of his personality is to be cheeky and flirty with everyone and he loves to tease and goad Ju specifically, which does in turn make her special (especially to us, the audience). He loves going round and round with her, 'cause her responses and reactions are so cute. It's like the highlight of his day.
At the moment, he looks at her like this little adorable puppy he wants to cuddle and chase and nag but also help take care of. So the hug/grab/snuggle had to be about him wanting to see how she'd react. He could've done it once and got his giggles but he did it twice, which means he had a purpose. That's probably why he says Ning's name. It's like almost from the beginning he was testing her character and his theories of who he believed her to be. As far as I'm concerned, he's been "interested" in Ju from the beginning but he has a girlfriend so that interest is compartmentalized; first as an odd girl at orientation, then a freshman in his major and by the end of the episode, his mentee. And I like that about the progression (which might also explain his feelings growth) because now that he is her mentor, he gets an excuse to seek her out and talk to her and get to know her better, in a comfortable, harmless way, that has nothing to do with him being a boy and her being a girl but just as two people with similar interests. So once he and Ning do separate, all that really happens is he's able to see and interpret Ju and the things she does slightly different because he's no longer orbiting someone else. Which totally works for me
