Nagito proposed to you earlier and after months was your wedding.

you two were getting ready in seperate rooms and you both were very nervous

Nagito was getting ready with Hajime's help and you were getting ready with Chiaki's help. You two also helped them when Chiaki and Hajime got married so it goes in the other way too!

Nagito was wearing a white suit with black pants and he put his hair in a ponytail! How cute.

You were getting ready with Chiaki and she was also comforting you a little that everything will go fine.

Chiaki: I'm absolutely sure Nagito would love how you look. Everything will go right!

She's quite good at comforting
