Shounen ai

hi anyone knows this shounen ai where they both are in high school, the other guy is blonde (or light haired) and the other is black haired, blonde guy accidentally poured water on black haired guy who was sort of crying near their school pond, turns out this black haired guy is sad bc his step-brother is going to get married

the whole story was pure fluff actually, the black haired guy was sorta cold and blonde guy was very welcoming and kind

i was reading a shounen ai earlier and was reminded of this masterpiece, does anyone knows it? bc I've read it a longgg time ago (︶︿︶)
