Kimi wo Aishita Hitori no Boku e Episode 1 Discussion

From my understanding, we have 2 Koyomis. At the age of 7, they chose to live with different parents. In world (A) he chose his father and in world (B), he chose to live with his mother and grandfather.  There are other minor differences in appearance too, for example, Koyomi from world (A) has brown hair and green eyes, while Koyomi from world (B) has black hair and brown eyes, and he has never met Shiori.  Also Kazune in world A has brown hair and red eyes and world (B) she has purple hair and blue eyes. In the first experiment, Koyomi transferred his consciousness to the parallel world (B) and Koyomi, who belonged to world (B), transferred his consciousness to world (A.)  In world (A), Koyomi never married, but Koyomi, from world (B), never met Shiori and married Kazune.

I just want to know, did Koyomi and Shiori marry each other in a parallel world? T-T

i watched this first. it was a pretty good introduction and i'm not confused, got the whole scope of the situation, at least i think so. 
about to watch boku ai, let's see how that goes.

i liked shiori and koyomi scenes a lot, sad it got cut short. seems this is the bittersweet end. i also liked kazune though. 7/10 for me, music was great as well.
