Gng u didn't need to point out that detail
I think it is to show that even though he chose to stay with Beom, he is in reality alone.. Because Beom is not actually a person, but a spirit.
Spirits don’t have reflections prob
I don’t think it has a major hidden meaning
Beom doesn't have a reflection cause he's a spirit (that's actually how geonpil found out that he's not the real hyung in the early chapters). Other people can see beom though, so he's kinda like a vampire.
Ok wait I’m so confused, it shows Geonpil at the end with no one in his arms when he was holding beom? Someone explain please!
