So the second story is telling us how Yashiro started to like Yamashiro, when they showed the "fight scene" it was a flash back of how Yashiro first saw Yamashiro in the first place and how chose to be an architecture instead of going into law so he can make Yamashiro fall in love with him
And he pays the electrician guy about $1k US to let him in and have a second go at Yamashiro. Yamashiro has figured most of that out, and it ends with Yashiro saying he'll never let Yamashiro go.
I don't understand the time line of the 2nd chapter. Can someone please explain to me? Thanks.
