Ohhh, i can see this getting dragged out for another volume. If anything, i think this type of development is typical, but you can actually still make a good story with a love triangle. Either way, im sure everyone will get a "happy end" 😎👍
On another day of "introducing a losing heroine when there is already a definite winning heroine but I have to write something for this chapter, oh, she could've been the wingman or had her own side plot? never heard of that".
good thing most don't give a damn/even remember about her though.
