He definitely sees it. he just doesn't realize it yet. but when she told him off, he came off to me as like well I didn't mean it. but still didn't say sorry....but he Lowkey panicking that she's going to leave. so the exam cheating makes sense now. cuz him "helping" her isn't enough to get her to stay.
he is sooooo panicked that she is going to leave omg the way he was like losing his cool and blurted out "mat jao na" and then tried to put his cool guy, reverse psychology hat back on!! he is literally like soooo worried of her leaving omg im living for this let him keep worrying and spiraling lolololol
