Does anyone like watching a sweet, kind hearted girl, who will get their heart broken, have this fleshed out Story line? They always add a "Second Girl" who you know will never have a chance, at best they'll have her hook up with another side character after getting her heart broken. They are used like cannon fodder, to absorb the bullets of anxiety and rejection and to make the MC realize their "true" feelings for the Main Girl.
I call this Manbagi Syndrome.
