Haruno grew up constantly moving, couldn't stay and make friends, no wonder he has issues like that.
But now he made a promise to get back with Rinko, so he has a reason to stay.
Rinko again, is far more mature due to her circumstances, but can't enjoy life since she was robbed of her normal childhood.
Such a blissful moments, but really will come down crushing in...
Another smile that needs to be protected at all cost now.
Thanks for scanlation!
