The story seems quite interesting, seeing her development and all, however i still agree with other comments regarding her view on responsibilty and her boyfriend.
The MC may be looking all nice saying she wants him to keep studying and that it's her responsibility, but I believe that that's bullshit.
Most of the people here I assume already know that all she is going through is her own fault in a way.
While she may have supporting friends, it's not the same having the support of your family and obviously the boyfriends' , whom , i repeat, SHOULD be informed of this.
But well, as said in previous comments, it's just a manhwa, right?
Just wanted to vent a bit.
Talking no jutsu, please work in this manga as well ... Save the poor babies :c They've gone through too much already
