Seojun talking about being busy from his job definitely rose a lot of red flags. Also him talking about how he will make her the happiest girl. Too good to be true. Could already see some conflict happening between Jugyeong and Seojun.
There's actually nothing wrong with Seojun being popular, he makes time for Jugyeong but the fact that he is a rising star, fans expect a lot including him being single. It's toxic actually, although I expected this webtoon to be different since it's already 2020, people should be open minded already. This is cliché but ST Ent. would talk to Jugyeong to break up with Seojun.
Yeah, I'm kinda sad that the story is taking such an obvious route. I suppose this is valid though since this is South Korea and they may still have that close-minded attitude. Good to spread more awareness to the rest of the world.
So are we gonna drop the idea of Jugyeong breaking up with Seojun because of his popularity? This is obviously a premonition that she would slip away
