A Song for a Kingdom Now Lost

One day, Utena receives a love-letter from a guy. And the guy turns out to be Wakaba's childhood friend, Tatsuya, who she calls "Onion Prince". The reason why she named him "Onion Prince" is that when they were very young and she was made fun of her hair as "Onion Headed", he helped her out as "Onion Prince" (but the flashback doesn't look like...). Gradually, Utena figures out that Wakaba is still in love with him. Utena tells Wakaba to be more honest. Besides, Utena also finds that Tatsuya is actually still in love with Wakaba and the reason why he sent Utena a love-letter is to get close to Wakaba. Then Utena tells Tatsuya that it's worth confessing his feelings to Wakaba because Utena is sure that they are both in love with each other. Now what's left is that Tatsuya confesses to her on the hill with the legendary tree. So far such a beautiful story! However...
