Yes, there are some mangas with similar themes. But they might not be very common.

They might also have to deal with the reactions of people around them who are surprised by their transformation. Additionally, it could explore how their relationship changes as they experience this new stage of life together.

It shows real-life love and emotions. You can relate to their simple but sweet moments.
