After see so many complaints I finally check Leah ending myself. And it isn't bad. I myself did a lot of things and overcomed lots of problems to maintain long distance relationship with my girl. It did seem no hope and won't work at the first time, had to find ways to solve problems even not existing in normal relationships. The ending story isn't as smooth and joyful as early stories but I feel it very real.
Make an assumption here. if someone who is being bothered by long distance relationship problems now, accidentally see this update , I think the ending will give him a lot of hope and faith.
so maybe it isn't that bad, just not very in line with previous story style (and too rushed to end )
