Goddammit help me remember

Hey everyone, seems like I read one of my favorite wholesome Mangas before I created an account and just realized I don't even know it's title to find it again, so you cultured folks may be so kind to give me a hand?

Characters: one of the mc was a short curly blond boy, the other mc was a slightly taller straight black hair boy, and they shared a girl best friend that was red/brow haired and supportive of them.


Plot: middle school/high school peers start to figure out they have romantic and a little of physical attraction for each other.
It has no nudity nor smut of any type!
It was a pretty short story (3-6 chapters at most from what I rmemeber).
I remember the black boy started to realize/question his attraction for his friend when he saw the blond changing his shirt for gym, and another scene in which they were both put to clean the pool or something and they messed around and fell together and they got all flustered about it. Also, when they told their girl friend about them starting to date, she kinda said she already knew since she's known them all their lives and she could see it pretty easily.

I also rememeber this art page which was of these 3 characters walking down the stairs on a snowy day, with full winter clothes.

I just remember feeling very fuzzy and warm in my heart while reading this, so if you know what it's called I would appriciate it for you to drop the link.

Thanks for reading.
