If Nangong Jin had no heart, then why would he go to such lengths to find these fireflies? You must know, it's winter now—where could these fireflies have come from?
So, whether he has a heart or not is now clear as day.
If a man doesn't love a woman, he wouldn't go to such extravagant lengths to create romance for her.
What's even more touching is that Di Jinxuan boldly and assertively announced her relationship with Nangong Jin to the public earlier today. Then, in the blink of an eye, Nangong Jin used this overwhelming romantic gesture to propose to her. Clearly, these two events were unplanned, because otherwise, Nangong Jin wouldn't have been so visibly startled when Di Jinxuan made her announcement.
And Di Jinxuan certainly didn't know that Nangong Jin would prepare such a gift, nor that he would propose; otherwise, she wouldn't have been so surprised and moved, crying tears of joy.
So, does this mean that today's surprises were completely coincidental?
