Is love in The Son of the Weather an equivalent exchange?

I don't think the love in The Son of the Weather is an equivalent exchange. Before the animated film "The Son of the Weather" was released, many people foresaw the polarization of word of mouth. In fact, Makoto Shinkai also followed the principle of "equivalent exchange" in the process of writing "Children of the Weather". It is human nature and the most ideal state to reciprocate, express goodwill and return goodwill. However, I don't understand this. Keisuke chose her daughter to give up that man, which seems heartless but understandable. When the value balance is tilted, "equivalent exchange" is impossible. ?

"Equivalence" depends on everyone's different values. Someone is willing to pay 20 thousand yuan for a sunny day, because that day is the most important moment in her life. The audience will not doubt such a decision, but they have a rather slight comment on the ending of the whole story, which is also influenced by the ultimate values. But love is definitely not the same exchange. Makoto Shinkai, as always, is good at depicting the inner loneliness of the characters, and The Son of the Weather still inherits this point. But when lonely people get together to enjoy their youth, the interpretation of "love" is not as touching as the previous works. Characters do what they should do and get what they expect in return.

Almost all the emotional interactions between characters are completed through "communication", and the hero and heroine in "The Court of Words and Leaves" have not abandoned the secular rules and are braver to each other. Not to mention the tacit understanding between the hero and heroine in Your Name when saving the town. The love in The Son of the Weather is that if you save me from the sky, I will wait for three years until you come back. This kind of "exchange" or "grateful" love has its rationality and legitimacy, but it is difficult for people to feel it.

If I give a comprehensive evaluation to Son of the Weather, I will like the unparalleled spectacular scenes and gripping and touching stories. There are even many eggs that only real anime powder can notice. However, this is not a qualified romantic movie. If both men and women can give full play to their initiative in the ending, I will be even more moved if their happiness is not based on the destruction of Tokyo. So I don't think the love in The Son of the Weather is an equivalent exchange. The above is purely a personal opinion.
