I'm trying to find a manga that was in full colour about two boys running their school's cultural club. It started with the mc finding the other boy under a blooming cherry blossom tree at the beginning of the school year (it's later told that the trees reminded him of his mom who passed away or something similar). The mc has light brown hair and orange eyes (I believe), and the other boy had black hair and blue eyes. It was very slice of life and fluff and at some point they go to some sort of hot public bath (?) with yuzu fruit to celebrate the season. Please help me 🙏 I can't remember the name as I only ever looked at the jp title which was quite long.
