So it sounds like we've reached an agreement on almost everything. There are still a couple things I'd like to talk about.
> More noble and handsome than a girl has any right to be...
The important thing now is to match whatever went out the door in chapter one. Consistency is more important than these essentially equivalent word orders.
>平坦すぎて
>It's too flat and predictable.
If you truly feel that using "flat" is too confusing in this case, try "My life has gone flat." I don't want to draw the phrase out; it should be short and punchy, like the original's.
For what it's worth, I use "handsomer," and "more handsome" sounds wrong to me. Maybe I'm weirder for it; oh, well.
I also consider myself a mediocre translator, and frequently encounter Japanese phrases that require a lot of work for me to decipher; that was certainly the case with this one. Accordingly, I'm very ready to believe that I've misunderstood something when there's a major change during TLC. Hopefully, things are now both readable and reasonable consistent with the original.
