I know for sure Blondie doesn't have feelings for Soo Ae. As am sure someo of you would think that he's in love with her but he's not. He likes her yes but as a very close friend who's comfortable to hang out with. Other than(the one who shall not be named) Soo Ae might be the second female who habours no agenda regarding Blondie. She genuinely likes him as a friend creating a more comfortable environment for them to relate to each other.
That's just my opinion 🤷♀️
