HELP ME FIND THE TITLE PLEASE!

Does anyone here knows the title of this shounen ai? The guys pretended to be eachother's boyfriends at their school. Idk they did it for some reason lol. The art style of this manhua is very light and has pastel-like color pallet, almost the same with Here U Are's art style! I know gave poor clues coz i have poor memory too but please i hope anyone knows what I am talking about
