FudanshiHoe's Things

Soooo I'm searching for this very specific manga. It's a very old yaoi manga I read a long time ago in my old ipad and really badly want to read it again. I particularly remember it was a collection of different stories. One specific chapter was about this divorced father and a gigolo. There was a scene were the father brought flower to meet his kid (and to go to an amusement park??) but the kid was bratty and they ended up fighting. Then he ends giving the bouquet to the gigolo dude and that guy ends up falling for him or something. Any idea??
