You and Dazai were both in a relationship. A secret one in fact, reason is well..You're in the Port Mafia while he is in the Armed Detective Agency..So that makes things a little complicated.

You manged to get out of the Port Mafia headquarters and went to the export docks where you wanted to meet Dazai. Dazai was already there but he was just being quiet to not be caught..When he saw you he immediately smiled and gestured for you to come to him from where he was..
