Introducing: The New Sweet Heart Skin.

Sweetheart skins are first introduced in league of legends through the girl characters such as Vayne, Varus, Ashe. Inspired by the valentines day the in game effect mostly seen by a plenty of heart designs. The good thing in this new skins is Rakan and Xayah is a good partner to each other, meaning that they excel in lanes and actually in lore, xayah and rakan have connected lores. So I can conclude that having sweetheart rakan and xayah skins is one of the best ideas in league of legends since everybody know that they are couples.
