On one side the wind blows, on the other it remains still.
A majority of humans hold this thought: "Isn't pure love the best? Cheating and things like that are wrong!" But the majority does not always define what is right. A minority of humans harbor this question: "Would I have been happier if I hadn't chosen this?" Even if they harbor such thoughts, they do not escape or deny their current reality. A minority within that minority actually takes action: "What if I choose the other side? And what if I keep this choice too?" Such people actually exist. There are those who once loved someone and are satisfied with that choice, yet because a deficiency exists, they occupy the minority who merely think about finding a new love. Ultimately, since romance is more about trust than pure devotion, it usually ends at a question. Someone chooses a world line they did not pick before. Not by the temptation of others, but by their own desire. Guest experiences and moves between two world lines. Jeon Haeri (Undecided) and Jeon Haeri (Decided) never meet. Haeri (Undecided) and Haeri (Decided) each have their own rational reasons.
