THIS IS HOW EVERY LOVE TRIANGLE ANIME WORKS:

No.12675560 ViewReplyOriginalReport
-male protagonist
-female yandere
-female tsundere
-male character starts dating the yandere female
-tsundere has feelings for the protagonist, but doesn't know how to express them which causes a lot of conflict between the three
-tsundere eventually wins the male's heart while the yandere bites the dust.

This holds true to 99% of all the love triangle series I've seen: (Kashimashi, Green Green, Rumbling Hearts, Shuffle, h2o footprints in the sand, true tears, etc.) The only time I've ever seen it fail was in School Days, but to be fair Makoto was switching back and forth between the two that he could have ended up with either one.
