The first page looks like a female student has made a Love potion and a teacher is scolding her. It then goes to show a storage room that we later see where the potion is being kept. Then the first story starts.
Act 1: Remus x Sirius
After class MWPP are eating and it looks like Remus has run of of drink. Sirius finds (I'm not sure if he knows what it is or not) a bottle and gives it to Remus to drink. After drinking it, Remus collapses to his knees holding a hand to his head. Everyone rushes to him to see if he is okay and the first person Remus sees is Sirius. Remus leaves and contemplates his feelings when Sirius comes to check up on him. Later in the library Sirius confronts Remus, but Remus grabs hold of Sirius and trys to kiss him, but somthing stops him. James then talks to them knowing that Remus drank a Love Potion. Sirius is embarrased, but the others seem to think it is funny.
Act 2: Draco x Hermione
In the second story Draco is searching the storage room for something when he comes across the Love Potion bottle and decides to drink it (Is this bottle even labeled??). After feeling weak and dizzy, Draco looks up to see that Hermione is coming in looking for something as well. He later finds that he keeps watching her and starts to panic about what his father would think and becomes misable. He then literaly runs into Hermione knocking the books from her arms. He picks them up for her while shakingly tries to tell her something. Ron and Harry find them and Ron gets defensive yelling at Draco. Draco then pulls Hermione to him and loudly declares something. Ron and Harry are in shock and Hermione raises her eyebrow at Draco and steps away while he tries to explain. This get Hermione's temper up and she punches him to the floor. Ron and Harry are amazed as Hermione storms off while Draco is on the floor shakingly saying, "why?"
Act 3: Harry x Severus
In the third story, Snape is having the class make a Sleeping Potion. Harry goes to the supply shelves to get the ingredients and finds the Love Potion bottle. Snape comes up behind him and Harry hurriedly grabs the rest of the ingredients including the bottle. When coming back to his table Hermione questions the bottle. Harry is made to taste the potion they made in class (which seems to have some of the Love Potion in it). Snape yells at Harry and when he turns to answer him he "sees" him and stumbles out an answer. Later the boys are back in their dorm room studying when Harry decides to visit Snape on the pretense of asking for help on his Potion's homework. Snape notices Harry becomes agitated when their hands accidently touch while pointing to something on the page in the book. Harry starts declaring something which thoroughly shocks Snape. Just then Remus Lupin(?) comes in to visit Snape through the floo. He sees Harry holding Snape's hand and starts yelling at them. Snape gets defensive explaining to Remus when Harry starts explaining on his own and shocks the adults. Remus playfully turns it aside to the shame of Harry. Remus convinces Harry leave while Snape and Remus leave and talk while walking down the hall.
