Sylvain

Caring for his friends and admired as an older brother figure in his class, Sylvain is a perpetual skirt-chaser and often attempts to woo women with sweet words to a fault, with the most notable example including Ingrid's grandmother when he was only eight. He is fond of women but his easygoing, shallow, womanizing behavior stems from the fact that he feels unable to form proper romances, and so he dates around without any particular commitment. Despite his light-hearted manner, he is often inconsiderate with his words around women, which cause him unintentional harm - even admitting in a support with Ingrid that the truth hurts. This builds up unintentional notoriety on himself, such as Flayn avoiding him for that exact reason, even though he wanted to pass her a message from Byleth.

As the game progresses, Sylvain decides to make a change for himself by being who he is, and not what his Crest dictates him to be. Due to his philandering, his proposals are often met with skepticism, which in turn prompts him to provide proof that he intends to turn a new leaf. In his married endings, Sylvain treats all of his children with equal respect, regardless if they bore Crests or not.
