Rukia like question

So I'm searching this manhwa that's about uni school life and romance.
I don't remember very much of the manhwa but I remember this part that is flashback of MC's past. So she had this best friend that had a bf, one day the bf contacted mc with the excuse of wanting to buy a gift for his gf' birthday (mc best friend). Mc accepted and then the bf continued using all types of excuse that are about 'for my gf' to see her again. Mc thought it was strange but bc her best friend (gf) told her that her bf is always busy and all. So mc decided to end all this hang out saying that she isn't his gf' but then the male confess that he's in love with her. Mc refuse his confessions bc he's her friend's bf. The gf discotthey were meeting and so the next day, at uni she embarrassed the mc with everyone watching by yelling at her that she was trying to steal her bf and all. The bf try to defend mc saying it was his fault and she didn't do anything but gf got even more angry.
After this mc was kinda traumatized.

I don't remember anything about the main story lol, as I said before this is just a flashback of mc's past.
