Bird-chan's Favorite

I'm looking for a yaoi manga where the MC goes to a school field trip; and he is paired up with the popular guy in the hotel room. The MC takes the situation to his advantage when women come to their shared room and he gets excited, but he's disappointed when the teachers come and everything is calm. He goes to sleep and in his sleep he is attacked by the popular guy.
Please, if anyone knows.
Please be generous enough to leave the link below.
THANK YOU!
