flamebringer is a bottom

The story goes like this: The seme who is an Alpha got tricked by his friends to go to an Omega Hotel where he eventually had sex with an Omega who is much bigger and more muscular than him. The seme was feeling guilty everytime he meets an Omega because of a past trauma, well, he's a good Alpha. The Omega male was pretty fond of him so they became closer and hung out at the park or something. I really want to read it again to know what happens when the Omega confessed to the Alpha but I forgot the title ╥﹏╥... Please do help me...
