It's "After Slaying the Demon Dragon," sung by Amy, the top idol of Azure City. The lyrics tell the story of the protagonist's teammates who sacrificed themselves in the battle to slay the demon dragon. Only when they arrive at the dragon's grave to pay their respects do they realize...

It turns out that in my heart, the other person was no longer just a teammate.

Only after killing the dragon and putting down his sword did he realize his true feelings.

It's worth mentioning that the protagonist is male, and the one who died was a muscular tiger-tribe strongman.

At the same moment, in the control room, a girl with black hair and a black dress, holding a parasol, muttered to herself, "Miss Aiko, this is all I can do to help you."

Beside the girl, a minotaur in a black suit, covered in sweat, silently apologized to the unconscious staff member in the control room.

Amy's soft and melodious music drifted in from outside the window. As Linda listened to the piece, a strange emotion welled up inside her.

He got up to pour himself a glass of water, but heard a snapping sound.

A small booklet with a yellowed cover fell out from between the pages.

【Echo's Revenge Diary】.

Linda bent down to pick it up, stared intently at the booklet, and hesitated for a while.

His original plan was to take some time later to send the suitcase and diary to Nanyan City and return them to Ai Ke.

But the diary wasn't locked, so I could just look at it without anyone noticing.

There is another possibility: this was deliberately left for Ike to keep.

Various ideas flashed through my mind.

Linda took her diary and sat down at her desk.

Opening the first page, one is greeted by large red characters, written with force, and the paper is torn in some places, revealing the anger in Eiko's heart when she wrote them.

The content of that line of text caused Linda's face to twitch, and a series of question marks appeared in her mind.

[Linda, the culprit who hurt the fragile heart of this young girl, I will make you pay!]

Linda scratched her head in confusion.

When did I commit this sin, Eiko?

As you continue reading, with Aina's furious account, Linda finally recalls the reason why "that thing" happened.

One afternoon more than three years ago, Ai Ke arrived in a wheelchair from outside the rented house and greeted him with a smile.

Just then, he overheard a passerby saying that his sister had fainted at the market. Anxious, he pushed Ike aside and rushed out.

"It's a misunderstanding," Linda sighed, her head aching.

The following content is similar to Ah Q's autobiography, with Eko smugly imagining various victories. For example, when Linda massages her feet, she is a "poor little dog"; when she is engrossed in making a strategy guide, she is a "pathetic working person"; Leah is a "brainless red-haired fool"; and Chrona is a "mischievous girl who will never get married".

Of the entire Snow Goose Adventure Team, Ai Ke was practically the only normal person.

Linda was both amused and exasperated. The ever-smiling Ai Ke had so many hidden thoughts beneath her mask.

While trying to tease them, she also had to maintain a kind and gentle persona. Just reading her diary, Linda felt that Ai Ke was living a very tiring life!

When I was halfway through the diary, something changed.

Each of the previous pages had a considerable number of words. But this page only had a few lines.

Linda glanced at the rest of the text and saw that there were only five or six lines at most, and often only one or two lines, or even just the words "sunny weather".
