@Romance lover Yes it is, but it signifies that light exists even after a star dies, be it due to the creation of another one from the debris or be it another star replacing the former's position.
(dying stars eg-> the yellow hair guy and the giant black guy) (new light eg-> MC and tht random kid at the end).
the story is good.
you should read "One Room of happiness" its a kinda romance but slice of life. and it has a depressing ending too. there is little to no fight scenes.
