Dear lord, she is 20 years old and yet she acts like a brat. What's the issue even if she becomes the 'loser heroine'? The title was decided by players who were like 'oh look, he didn't go back to his first girl, poor her', but because she doesn't show up later she has infinite possibilities to become whatever she wants and live however she wants. There was no need to avoid her friend and do all the background checks, etc...
