The end is the most f up, I even searched for the explanation but I got disappointed, the reason being " they had to fulfil the character" or "she had to fix her relationship" because it doesn't change the fact that the ending was not fulfilled, they slapped a " she ran away " and the end, the least they could do is show her come back and start a family with Ryuji. Sorry if I'm ranting, but it was so good, but I don't understand how they could ruin the ending like that.
