Hey I'm looking for a yaoi manga. Here's what I think I can remember from the plot:
There was a young man who recently joined a company, and he is looking for his "daddy long legs" who supported him through the years but what he doesn't know that his boss (or maybe it was the company president) was his daddy long legs, and his daddy long legs has been in love with him for a while. He keeps sending his daddy long legs letters of thanks too for his support )and to update him on how he seems to be falling in love with his boss lol) without knowing that it was him the whole time
If anyone knows the title please lmk

Guys I found it it's called
Darling long legs
