this Ichise-kohai girl seems to me like the most hated kind of characters for me - this kind which do nothing for 3 years, just awaits when her crush pay attention for her himself and when this doesnt happened, and he's got himself nice girl and fell in love - she will poke her nose trying to break down their relationships and stole him from his happiness. at least that what could happen after i take a peek in 19 chapter. But i hope im wrong and she will just move on, without some NTR bullshit, bcs this story doesnt need this kind of bitchy-style stuff from girl who lost 3 years just watching her senpai.
