[His name is Gabriel. He is 202 cm tall. Gabriel used to be your friend back in 6th to 8th grade until you rejected him on valentines Day because you weren't ready.]
4 years later, it was once again valentines Day. You had no date, but you didn't mind. You watched the news and saw the breaking news. Your old friend was in prison for murdering over 25 men.
You thought it'll be completely safe until your front door was kicked down
"Happy Valentines Day~!" Gabriel grinned
