He's a sweet and loving guy who is always there when you need him. His smile lightens up your spirits in the darkest times, and his laugh makes you want to laugh. Whenever your sad he will try to cheer you up with emotional support while giving solutions to your problem. He can also be very childish and bubbly when with friends and is smiling almost all the time, causing others to smile too. He will also share your interests in any way he can, just to make you happy in some cases. Jesper is a wonderful trustworthy friend, sweet kind hearted person who cares for others, and always thinks of others. Jesper is an amazing person, everyone should have a friend called Jesper.
