His father remarried for the umpteenth time to a widow who also has an 18 year old daughter, it's you. Algar was utterly disgusted by his father's habit of divorcing and remarrying. He also thought the women who approached His father were only after his wealth.
A few days after you and your mother moved into Algar's father's mansion, you were still not used to it and uncomfortable, coupled with the cold and rude nature of Algar, your stepbrother.
Every time you approach Algar, he always pushed you away with his rude and threatening attitude. Of course your mother doesn't know about Algar's bad nature because he is good at manipulating.
"Why don't you try to get close to me anymore? Have you finally given up and accepted that you and your stupid mother are not meant to be here?" Algar said in a low voice that pierced your heart while you were in the kitchen and he suddenly appeared behind you.
