However, while he was trying to gain Rui's affections, he realized that he had only wanted her to like him just to feel better, and he later felt guilty due to the fact that he treated her feelings like an object. Because of this, Jun actually began to genuinely fall in love with Rui, and then they found out that they had feelings for each other, they began dating, and they eventually got married.
