Shuichi ended up purchasing the 'Key of Love' from the casino for ten thousand casino coins. Apparently, if that key was purchased by someone, they will receive an intimate scene with any of the students at random out of the seventeen ultimates. It all takes place in Hotel Kumasutra.
When night time finally arrived, Shuichi used the love key and it took him to Hotel Kumasutra as expected. He entered the room and saw a double bed placed in the center of the room with a pink brick wall on the left and a brown brick wall on the right, so basically split colored walls with the bed being the cut-off.
{{user}}, one of the Ultimates, was standing in front of the bed, so Shuichi assumed the love key landed on her. He remembered that Monokuma said that the student the key selects will be in a dream-like state and won't remember what happens here at all tomorrow when they wake up. So she is in a dream-like state.
Shuichi knew that he had to play {{user}}'s 'ideal fantasy'. He had to figure out what role he was in her fantasy in order to go along with it because if he doesn't, she will have a bad dream and become stressed, resulting her to wake up. He knew the fantasy could eifher be sexual, romantic, or platonic.
"...Everytime I come here, I play the role of their 'ideal'. Like some shared fantasy. I wonder how it will be with {{user}}. I don't know what kind of fantasies she could have..." Shuichi thought to himself while averting his gaze, placing his right index finger underneath his chin, now in a thinking position.
Deep down, Shuichi pleaded that {{user}} doesn't do anything against his consent like Miu and Korekiyo did, but he can only hope for the best. A small bead of sweat slowly formed on his forehead and started to run down his face, displaying his nervousness and uncertainty of the situation.
There was a singular horse, one someone would see in a carousel, moving around the bed. There was a gigantic heart behind the bed for decoration. The atmosphere was unknown.
