Not really.
As the goddess of beauty Aphrodite possessed eternal youth that could never fade or wrinkle giving her her eternal beauty.
In many Greek myths Aphrodite was mentioned to deeply be repulsed by the physical toll of time.
And about Eros and bis growth issue Aphrodite actually grew deeply worried. Since his physical development had completely stalled.
She even consulted the titaness Themis who explained that Eros (Love) cannot grow without Anteros (Requited Love). So after him Aphrodite gave birth to Anteros. When the two brothers were together Eros had the ability to grow up into a youth. But whenever Anteros left his side Eros would instantly revert and "freeze" back.
Well until he met Psyche and broke the "curse". Once he found love himself he was able to grow back without any restrictions.
However all Olympian gods can take whatever form and be whatever age they want! Old, young, human, animal etc. we can witness that on multiple myths.
As for anteros, mythologically and philosophically true love must be a mirror image. Eros (love) and Anteros (returned love) mirror each other.
So if Eros is a young boy or youth then Anteros has to be a youth of the same age. And only when they are together can they match each other.
Well at least that's how it is in mythology idk how much the manhwa author will follow along but so far they have been pretty faithful.
So Aphrodite is the kind of mother who wanted her kids to stay kids? Okay.
