Everyone will start at different relarionship levels. It depends on when your character will want
 to work. Soreally it's based on character, example being Kiku is an friend with everyone with exception of those who right after to school since that's when he has to go to meetings as part of the Yakuza. He doesn't work as much during then.

Romance can and WILL happen, I will make my moon go you two should kiss.
