this webtoon shouldn't have the Romance tag listed,though.
It's way more about psychology and human relationships outside of sexual attraction. The comedy tag seems also out of place, there isn't even anything funny about this story. It's cruel and harsh reality about RAW inter-human relationships (i.e. before the brain is mature enough to go on about it with reason and slyness).
In reality, Random Chat seems to symbolize the human gutter, where people self-censor themselves to attract others.
Sung Ah is a nasty b!+(# who's willingly backstabbing the guy who helped her out and whom she approached herself,
she should be ashamed of herself to not openly admit that she doesn't want to be friends with the MC.
She's not better than that psychopath Lila who's mentally abusing and manipulating poor introverted people to her will.
Both are making me sick, since I've had similar experiences in my high school days with women who were approaching me for their own benefit and then backstabbed me.
Such people shouldn't exist, but it's female nature to try to get the biggest gain through trickery (a lesson they didn't teach in ecology ), which most people sadly only learn via scientific self-study or first-hand experience.
I just hope the artist will make a grand finale where the MC punches Sung Ah in the face(or at least humiliates her harshly) when she finds out about him being her random chat partner and gets together with one of the two girls who actually care for him as a person.
Or we'll have a bromance ending with him and Tae Yang being best friends after overcoming both the bullies and the weird psychopath of a guy who's trying to bond together with Sung Ah, with the manga currently shifting more and more towards fighting [somehow reminds me of Lookism...]
