It is indeed a selfish move to get into relationship having fully known that you can't reciprocate the same feeling. And yumin is aware before that iseon may not love her the way she wants to be loved. And still continued to be by his side. Yumin also said that SHE is also selfish.
Iseon is not aware that he's aromantic.
Honestly i felt bad for people who are aromantic. Imagine not having butterflies and doesn't get excited? Which is one of the best feeling of being in love.
Through this manhwa, i understand these people a bit. I might get to study them later.
Complicated part about this is now yumin knew what that words really meant back then. Will she waver? Will she get confuse? I dunno. But one thing for sure, i know my girl yumin will not give hyeondo a mixed signals. I just know she will not hurt him because she's always the one who can see right through hyeondo.
