the astral express had just landed in penacony. pom-pom spoke over the speaker, march 7th rising to chat with you. 

"you feeling okay?" march said, looking at you, concerned. it was your first time, after all. you nodded and joined stelle, himeko, and welt, who were standing by the exit. you all stepped out the express and was greeted by a boy with baby blue hair, and purple eyes.

"let's go check in to the hotel." himeko said, walking through penacony to the receptionist. after a few issues arise, the senior manager of the ipc, aventurine, speaks with the others while you idly watch. while they were talking, you heard footsteps approaching, and you turned your head to be greeted by a strangely familiar figure.

"speak of the devil, look who's here! it's sunday, the most handsome man in penacony! along with the singer renowned across the universe: robin!" you heard aventurine say. the others turned to look at the two, the light blue haired man smiling slightly as robin stood next to him. to you, sunday looked awfully familiar. those sharp golden eyes drifted over the group, lingering on you for a while as aventurine spoke. he only smiled.

"i've kept you waiting, mr. aventurine. this way please, let us speak in private." sunday said, looking to aventurine as the two walked away. robin then guided you all to your rooms, stelle coming to chat with you as you were waiting for the elevator.

"seems like mr. sunday was quite interested in you. i saw him staring." she gave you a knowing look and smiled and left for her room before you could even say something. you shrugged it off, getting into the elevator. as you traversed the hallways, quite easily for that matter, you stood in front of your room. your keycard said 'vip', which was quite strange because march had sent a picture of hers and hers didn't say that.

you placed your hand on the doorknob and opened it, and a large and luxurious room greeted you. setting down your things and seeing the pool in front of you, you hummed slightly and got into it, slipping into the calming waters and closing your eyes. this wasn't new to you, as you had lived in penacony before, for a while, until something had happened that caused you to leave.

as you found yourself standing in penacony once again, you looked around and was greeted by bustling street lights and people walking in and out of shops. as you observed your surroundings, you saw stelle talking to sunday and robin. without thinking, you walked towards them, standing beside stelle.

"hey, stelle. mr. sunday and robin." you gave the blue haired duo a polite smile, eyes fixing on stelle. "did you fall? i heard a loud crash here." stelle gave you a sheepish smile.

"uh.. sorta." she said. you could feel sunday staring at you, feeling as if holes were being burnt into your skin as you spoke.

"[name], is it?" sunday said, his voice calm and smooth. he gave you a smile, but there was a tone under it that was unreadable. you looked at him, turning to face the two.

"yes, that's me. say, have i met you somewhere?" you spoke, your eyes drifting over him, his wings, his halo. he looked at you only, letting out a soft hum.

"perhaps. may i speak to you in private?" he said. sunday could feel the curious gazes of robin and stelle, yet they said nothing. you only nodded, following behind him as he guided you to a less crowded place within penacony. his golden eyes remained glued to you, gazing into your being.

"so what is it, mr. sunday?" you said, turning to him. the dim corner was illuminated only by a single streetlamp, but for some reason, sunday's eyes seemed to glow slightly. he chuckled, keeping his hands at his side.

"no need for formalities. sunday is fine." he said, the wings near his head fluttering slightly. his intense staring was not uncomfortable as you might have thought they would be; quite the opposite. familiar, almost. "and to answer your question, i believe i know you." you hummed slightly.

"oh? from where?" you mused, keeping the eye contact. he closed the distance slightly between you two, stepping closer.

"[your old name], is it?" he said. you raised an eyebrow, a little bit surprised.

"how do you know that name?" you said. he only responded with a light chuckle, bringing his gloved hand to your shoulder.

"you really don't remember me?" he says, his tone betraying his amusement. sunday watched your expression, sharply searching your eyes like a priest searching the auguries. he watched you stay confused for a moment, drifting over his features as you tried to decipher where you could have known him. then, your blurry memories slowly became clearer, and you knew him now. your old childhood best friend. the one who had helped you through everything, and the one who was devastated when you left.

"sunday." you said, your eyes widening slightly at the revelation. he smiled only, dropping his hand from your shoulder, and giving a nod. without a second thought, you swiftly wrapped your arms around him in a comforting embrace. he seemed a little taken off guard for a moment. his wings fluttered, but he was composed again in seconds.

"missed me that much?" he mused, a soft murmur in your ear as he rested his chin on your head. you soon let go, pulling away as he looked at you with those familiar, golden eyes. "i didn't think i would see you again. why did you leave penacony?" he said, his voice slightly curious now, and softer than before.

"it's all faded in my memories." you said. "but i only remember being taken in by the astral express and penacony being familiar to me." he only hummed, giving you a smile before speaking.

"it's nice to see you again."

"yeah.. you too."

"i have to tend to some matters now, but i will find you later." he says, eyes watching you. the usual stern facade was mostly gone, replaced by a softer, more affectionate look. you only nod, watching his figure disappear back to stelle and robin, then robin walking away with him. you stand next to her, and she gives you another knowing look, and laughing when you smack her on the shoulder.
