((I've had this idea and I'm gonna be playing with it))
Meeting
Mikado realized he didn't mind having to travel, not when the other was always waiting for him at the station, they couldn't quite meet in Ikebukuro anyway, both were a bit possessive of the other and prefered not to have their time interrupted
They talked while walking, the informant enjoyed testing just how good the boy was at deducing what he obviously had, Mikado didn't mind, he liked thinking about this things as well, knowing that the other was letting him see his work made life much more interesting
The first time this happened he had wandered through the city and bumped into Izaya, or rather the other found him, and at some point in their conversation Izaya had hid behind him as a bending machine fell where the informant had been so the older of the two had to leave, Mikado felt kind of lonely the rest of the way home, but god forbid him from admitting that, not that it mattered whether he said it or not, the informant would probably know either way, but he still found it rather embarrassing, he waited a while before connecting to see if the other was online, he was
The informant asked for him to meet him the following day on Shinjiku, and when he said ask, he actually meant it, which is to say a lot if you think it through. Interested he decided to accept the request and so their wierd relationship started
After that they met several times and had somehow made a silent agreement that they would see each other at least once per week, each for their own reasons, though at some point the younger of the two forgot what his were and the older decided not to take his into action; they didn't have a specific day or time, sometimes Izaya would visit instead and they would talk in Mikado's apartment, but both prefered to walk so Mikado traveled a lot more than the other, in this sence at least
