Saw the raws up to 20 and *spoilers* ofc I don't understand anything but I hate how little Ikumi appears and ofc he is this cold type of person. Meanwhile we are introduced to other characters that surround Tetsuo, who he is fine and happy with, and I just can't care and don't feel attached to grown up Tetsuo & his ambition at all. I mean at least if we had more Ikumi, I can't with glasses girl having more manga time than the other mc. I also don't want Tetsuo to 'win' over Ikumi at this point, he worked hard but crushed his friend's spirit in the process.
