long lost manga

I’m desperately looking for this manga that I read a couple years ago that I can’t find again. It’s short it’s like a high school romance where the uke is going to this shop after school and writing notes to someone else ( in the little customer book? ) and he thinks it’s a girl but it turns out to be this guy from another school with a scary reputation ( but he’s a actually a sweetheart ) and he eventually agrees to go on a date with him even tho he’s not a girl and the seme is like really into flowers and his parents own a flower shop or something. Sorry the details of this are vague but i swear it’s real and i can’t find it!! it was so cute and simple please let me know if yall know what i’m talking about (T_T)
