I started the film with just the sketchy synopsis, but was immediately reeled in with the storyline.
I like how the conflict was immediately shown when the two main characters were introduced. The writer and director did not waste precious minutes in fleshing out the characters and showing their motivations in the film. On first watch, it is seemingly a slice of life film and has a happy ending, but on the second watch, I grasped the feelings interspersed with the somber music (or lack of it) in the last few minutes of the end. The adopted son labeled himself a "nobody," and was desperately longing to have a family or at least a place to call home (as presented by him saying he will not leave), and with those things as his goal, he became the glue to the family. He became the son that was lost, the protector and the lover.

I think he don't love the older brother, but instead offered himself to fill what the older brother need.

oops! I rambled again.

Ultimately, I love this short film and wish to someday see this one be made into a longer film or a series.
