In the first track we are explained about the heroine's condition and her background with the guy here, which is her otouto a.k.a lil bro~
He got some extraordinary skill in designing clothes and gowns. He had dreamed to be a designer and currently (in the story) is attending a competition.
He won the competition and everything went well.. at first~
They decided to celebrate it in a restaurant when she suddenly fainted and her lil bro got to bring her home.
He made her a soup or something warm and made her ate it while asking whether it's good or not and talking about his designs.
The next day, he went into her room only to find her changing clothes..
He got panicked and still rambling to her, telling her to stay in bed instead of going to work.
But since she insisted because of the current project was very important, he gave in and made her brought his home-made-bento.
The next track opened with him asking her to hold his hand since he was afraid she would be in danger (yandere alert!!! XD)
He asked her what time she would be off from her work.
I think he intended to walk her home.
The next track, she found him waiting for her outside and he got cold since it's very xold outside.
He asked about the bento and he would make more special for her Aneki~
He told her about his works and told her about his plan on making his own brand~
Yet he didn't reveal the brand to her. He promised to show it to her first once it is made.
In the next track, he walked to her office again only to bring her his bento since she had forgotten to bring it.
He also warned her to be aware of some of her colleague in the office since he found out that the guy just looked at her breast.
Then, his yandere personality start showing up by keep asking her to walk home together with him
Luckily, there was a phone call from his chief and apparently there was some matters that needed to be done.
He kept warning her to stay away from that guy as he walked off.
They got some dinner together and when she stood up to cleaned up the dishes, he stood as well to prevent her doing the chores.
There, he started talking about how she would get married when she
actually got totally absorbed into her works in the office.
He mentioned her to use his dress when that big day came.
He showed her a princess gown he said to be a wedding dress for her.
She wondered why did the dress so fit to her body and he only explained that it was actually made for her. He insisted her to try it on and helped her wearing it.
He helped her to wear something and he suddenly mumbling about other guy looking at her exposed skin and made him a freak yandere again. Before it's too late and caused any unwanted freaking response from the heroine, he stopped and start made her wearing the accessories.
He mentioned how he would be lonely when that day came and yet complimenting how beautiful she was with that dress on her.
He also showed her other dresses he made and asking her opinion for it..
The next track started with her got jome and greeted by him. He explained that he had waited for her to have dinner together with him. She explained that she had had her own dinner.. at first he suspected it was with other guy but it turns out that she ate all by herself. She also told him to not wait her any more since she would be very busy because of the project. He got slightly mad since he thought she prefer to care more about the project instead of her own body.
That night, he made her soup and confessed how he loved her and she was the sole reason for him to work hard.. when suddenly she fainted again...
Feel deja vu now??? >=)
Turns out he "poisoned" her and had called to her work place that she was sick and need some day off. She stated that it's bad but he didn't care since he prioritized her Health and condition most.
She commented how he actually mad at her, which he countered and denied all the way.
He only asked her to keep listening to his words..
"I will protect you.."
The next day, he brought her some bento again when he asked her her feeling that morning since she didn't look well.
When she almost fell, he caught her and found her in sleeping condition again.
The next moment she awoke, she found him working about size for the clothes.
He became aware and asked her again.. Fortunately, our heroine wasn't the mere idiot heroine and started suspecting him and his bento to be the source of her unwell condition
She stated how this was actually bad but he started rambling like a psycho again and told her again how he would protect her and asked not to get out from the house.
This is where the story got branched out into two different endings: Happy End and Bad End
She was like "are you freaking nuts?!"
And he started explaining that he was the main reason why she got this unwell feeling lately (YOU JUST REALIZED IT NOW?!??!)
She asked why and he answered because he loved her and more bla bla bla and he would like to protect her..
When she only glanced at him with sad face, he started freaking out and that night decided to move out and disappeared from her life.
In the last moment, he thanked her and apologized to her to have such feeling
Later on, she came to a bridal shop..only to be greeted by him.
She freaked out of happiness and got some tiny lovely chat with her long-lost-lil-bro.
They even got some tea party together~
