It's sweet, but still, Kagami is so silly for keeping silent and letting Shingo get insecure (as he obviously would!). As for the last page... The nerve of him! Stupid Keiichi. *angry*
Yeah.. I ever mentioned that "Actually Kagami tries to protect Shingo from Angelo" in my previous topic here.. http://www.mangago.zone/home/mangatopic/1086705/
Later I also saw Kagami tried to avoid this-that, Don't let Angelo meet Jin.
In this chapter, Ei also did the same, didn't let Jin meet Angelo

As I guessed in my previous topic..
Actually Kagami tried to protect Shingo & Bro Jin from Angelo, so did Ei..
So Kagami chose Green Diamond to match with Shingo's eyes. Wah~ O(≧▽≦)O How Sweet & Romantic!
