Commentary:
Mako probably comes off as a bit finicky here, but I did at least point out his desire to tell give his family some additional info about himself earlier in this chapter. In any case, hopefully you're looking forward to whatever he has to say. Although it looks like it's already not that great news.
When I was writing Yuari's dialogue in panel 2, at first I thought it didn't make much sense. A few pages ago, she was shown to be assisting Mako in using a fishing rod, so you'd think she would have heard him say something earlier. But then I imagined Mako being silent and frustrated that whole time while getting help and it seemed fitting for him, so I kept it in.
Batuu: Oh some daddy issues huh? =w=
