Well because she just walked by Haebom without reacting in any way and was mentioning on the phone she'll tell them something, it would also exclaim why she did poorly at work. I mean obviously i could be completely wrong but it crossed my mind when Haebom said that he's sure that It's because she was taking on her phone that she just walked by him

haha as opposed to not being able to see I think she was just too focused on her phone call to notice Haebom. And she’s already mentioned that she wants to be a housewife, so that’s probably why she’s crappy at her work, cause she doesn’t care about it at all.
SPOILER
She quits without giving notice. That’s what she was supposed to meant by telling them. She just doesn’t show up for her work and then tells them through the phone while on vacation. The absolute worst yo.
Bruh is that girl blind??? That's why she wasn't doing well at work, because she can't see. If that's the case why didn't she tell them sooner whaaa-
