This is Four and X's wedding. (comment is on Water's anim here) it's mostly anime themed (Cause X is a weeb UWU) and Four is wearing a green suit with black pants,black shoes, a red bowtie,and a four leaf clover since Four's value is well four and he's an unlucky number (and there's a believe where if you find a four leaf clover it brings you luck) so yeah. (also on the arch there's a heart umbrella with Four and X under it it's basically Japanese equivalent to American's name + name lol). Four and X belongs to Jacknjellify
