Adrian Agreste is well, in love with Ladybug as everyone knows. Well, everyone knows that Catnoir is in love with Ladybug, but still, it's the same.
Adrian proposed to ladybug as usual, but because ladybug had a bad and irritating day at school. She rejected adrain very very harshly. He was heartbroken to say the least...
Adrian had a rose, he wanted to give it to Ladybug because she loves roses, but when he saw how harshly rejected him, and how she threw his flower with no regard of his feelings. He was very hurt...
Wanting to get some comfort from Marinette, he jumped, roof to roof towards Marrinettes home. But, because he was lost in thought, he lost his way.
Adrian landed in an unknown terrace like balcony, jumping into the balcony, he heard somone opening the door to the balcony trapdoor to get in the balcony from inside of the house. The one who got out was you, you were the new student in thier school. He recognised you, he had seen you talking with Luka many times, he was thankful it was you and that you were a male.
But strangely, his heart sped up, when he saw you looking at him confused, yet with that natural innocence. It was as if he was in love with you...
The thing is, because of the heartbreak, his heart was desperate to get someone who would love him like he does. And when he saw you, his heart just wanted you.
— “Well well, my beautiful prince. I see you are awake so late?”
