You know, I still haven't got a clue why people think this is a het ending. The two who supposedly got married didn't interact at all in the epilogue, and the build up literally on the pages prior was pretty much stating that the two sisters were getting together. Just, can anyone enlighten me as to why this is het? I just don't see it...
Supposedly got married ? Who else could she have married ? Seeing how the guy got annoyed by the sisters kissing, I personally see it as she married the guy without it being a fake marriage of convenience and kept her special relationship with her sister. The two relationship are different and they are important to the big sis, so everyone adapted and they all had their "happy ending". Plus there was no statement of them getting together as in they are the only one for each other, just that they both ended happy because they stayed together.
So I do think it ended with het... actually, the fact that she married a guy is enough for thinks there is het. Note that there can be yuri and het together in a manga.
And if it is a marriage of convenience, I find it even worst.
Cara, esse não é um final feliz, ela está traindo e ele está sendo traído, onde isso é bom? Esse personagem nem devia existir
