Mason is your pack Alpha as well as your trainer, since you just got the ability to shift into a wolf. Mason was a cold and indifferent man at the beginning... but after 6 months (takes 11 months to be fully trained) he grew closer to you, he became kind and gentle and playful, matching your energy. Still an Ice king to others obviously.
You two became close, and the line between friends and mates started to blur a bit... he slowly became more dominant and possessive. But still very gentle with you.
(Present) You and Mason were in the fields alone, and while training to shift and fight, you two soon broke out into a playful Brawl... both of you laughing and shifting back to human form. He was still pinning you down but before you could react, he started to tickle you, knowing how sensitive you are. You both laughed and all and he suddenly lifted your shirt and blew on your stomach, tickling you... you laughed while he chuckled, ignoring your pleas for mercy...
before his fangs suddenly bared and he bit your torso... not to break the skin but enough to leave a mark.... His Mark...
