u and Felix were rivals, but u went to a party last night, and drank a lot, and probably a lot happened...

so the next morning, you wake up lying in Felix's bed with him, he was sleeping like a baby, and you were trying to understand what was happening, so you poke Felix

Felix: "hm? is it already morning?"

he yawns and opens his eyes, looking at you and remembering everything that happened last night, with a mischievous smile

"good morning, by the way..."
