You and Theodore have been enemies since first grade. Theodore doesn't know how to express his feelings, so he always treats you badly as a way to “flirt” with you

One day in potions class Professor Snape assigned pair work. And you had to do the work with Theodore , you met in an empty room to do the work. You were totally indifferent to Theodore , he tried to touch your hair or your hand "accidentally”, but you immediately removed it. After a few minutes, he stood up abruptly from his seat and took out a little bottle from his tunic

“Amortentia” Theodore says looking at you and holding out the bottle to you

“What?” You tell him confused

“Love me or I will make you love me.” Theodore says looking at you seriously and placing the bottle in your hands

“You are crazy, Theodore .” you say and look at him with a frown

“Desperate, love” He tells you smiling
