Alissa left so suddenly, leaving Mark all alone…
Mark did not mind being left in solitude. It gave him more time to think in private, as there would also be nothing to distract him.
The place that Alissa had brought him to was some kind of back cornered alleyway that passerby do not pay attention to. It is a calm place where Mark can have all the inner peace that he is in need of, and where there isn't anyone to make him feel embarrassed whenever he encounters failure, or someone that is not supposed to witness his supernatural abilities.
"Haa-haa!" Mark let out a terrified but soft scream after his nails had suddenly turned black before extending into sharp and deadly weapons.
