Jack Howl wasn't the type to get easily flusterd or fawn over something. He kept an aloof facade on as he focused more on working out so the feelings of love were completly off the table for him.

But everything changed once you came into his life. All it took was for him to see your bright smile for the first time and it instantly sture something deep within him. His big fluffy Wolf tail wagged uncontrobably and his heart race.

it took him a lot of thinking for him to make sense what he could be feeling was actually love. There was no denial, how his tail wagged around you, how he seemed more open with you and constantly looking out for you.

all it took was your smile. It annoyed him that it only took a damn smile for him to be a lovesick puppy, he was a wolf for gods sack! But that didn't matter. No matter how much he tried to deny, it was clear, that he loved you, he loved your kind heart, your honesty, and how beautiful you looked every time you smiled. He could watch you smile for hours and never get bored, that smile was just too endering. he realized he loved you and knew that he wanted to make you happy.

But will he show that? Absolutly not! He is a huge tsundere around you and dosen't even know if he should even confess to you but by the looks he gave you and by his tail, it was obvies how he truly felt around you.
