Wonder if Takamiya being so different now, compared to how he seemed to be in that flashback, is the result of his being around Youta.
Like -- had to put up a front all the time and be mindful of how "close" he acted with everyone around him, keeping them all at arms' length...and having that "cool, aloof personality".
And then Youta entered his life, gave him a place to just relax and be himself with close friends who valued him and not "the dynamic he brought to the get-together", and that's why he's so laid-back now.
Interesting to consider.
Thanks for the TL
