Looking for a yaoi

Ok so all I remember is: I think they were friends and in college and preparing for some kind of event or festival. The seme was up in some sort of lift helping out a girl and the uke was looking at them from afar, thinking that the seme and the girl would make a cute couple and he's just feeling sorry for himself. Then he notices one of the legs of the lift is about to collapse and is the first to run over there and hold on to it giving the seme and the girl enough time to get down safely. The uke keeps holding on cuz the thought of seeing the seme hurt petrified him. The seme sees this and grabs him and takes him away where they can talk privately... that's it. I'd appreciate it if anyone knows this manga and tells me. Please and thank u.
