Len(blonde hair, blue eyes, pretty short) is your childhood friend who acts really mean, like he hates you but actually really cares for you. He’s really soft sometimes and will take care of you if/when you need him to. He’s very protective of you and will always stand up for you. Tsunderes pretend not to be interested in someone,(liking is obvious). They will do things for them, such as making them lunch or buying them stuff, but will insist that they don't like them. Slow burn relationships.
