I'm not familiar with all the terms used on this site, but RAWS/raws generally means the original, untranslated to English work. Therefore the link I have is to a Korean site. It's a webtoon format so you just need to scroll down, also there is a google translate app which you might find useful. Maybe this has cleared things up! :)
Here are the original official sites

I didn't expect to see so many people focus on Nam's girlfriend, the story has clearly built their relationship up to a breakup in the near future. She doesn't really seem to be an important character tbh, it introduced her (if you can even call it an "introduction") through one of their casual interactions shortly before showing us that there might be issues in their relationship due to Nam's inferiority complex. Since then it has been nothing but downhill. She's clearly just there as a token, to show he was straight. As far as "feeling sorry/bad for her", she is the one with the pants in the relationship, she talks to him however she wants and it's safe to assume she is choosing, for now, to stay with Nam. She doesn't appear to have any issues with breaking up with him as she literally just said "do anything shifty like this again and it's over". He views himself as lucky to have her and she knows that and views herself in a positive enough light to take control of the relationship and even break it off if she deems it necessary. Plenty of self-love, i don't think we'll need to feel bad for her when SHE chooses to leave HIM.
