They kinda didn't explain why he was having nightmares about Takahashi or why he called him. I'm guessing maybe it wasn't happening that often but the MC was fixated on it because of his insecurities.
the last chapter kind of boring, there is nothing much in it and wasted pages only to show all the characters and the drawings, i was hoping for more stories about them and if there will be kids or no, so i was little disappointed because it ended quickly.
is there gonna be and more extras or what???
