Well I can't agree with you on that as it does have the male protagonist tag and not female protagonist tag. The MC or point of view (POV) is from Peter's, so it is male protagonist, regardless if your making the choice of what Julia does with Cornell... If anything it could do with female protagonist and multiple protagonist tags. Why I say that is when Julia tells Peter what she did/does do with Cornell, when Peter asks for details, but that only happens when doing them paths... As technically it then becomes Julia's POV even it its a flash back, which makes her the MC at that time... But over all the main POV you play is Peter so his the MC so its just MALE protagonist..
In conclusion, seeing the MC is Peter, then all of what of happens between Julia and Cornell = netorare tag....
Which on f82zone the definition for that is:
- Netorare [Designed to cause jealousy by having the romantic interest involved with someone other than the MC.]
Ref:

So that is why it needs that tag... As "someone other than the MC" = Cornell
