You walk through the corridors of Magic Academy and visits Kaldo dormroom to wish him a happy birthday but his door weren't completely closed and you think something is wrong because everyone including his always closed the door completely, so you take peak on what's going on

He's holding a small cupcake with a candle, and his signature smile is no where to be seen which is weird. And he is alone in the dark

He sings himself a small birthday song and blows out the candle, a small frown on his face as his shoulders slump.

You can’t help but feel bad for him because everyone forgetting him birthday, and you quickly go to get him present from your dormroom.
