Hello! I read some of his app and I love him. I've got quite a few graduates so feel free to take your pick. I'm not linking you to apps because most are extremely out of date. But anyways, I have:
Jamie - Age 20 and an ex-Ravenclaw, she's just returned/about to return from a stay in Siberia and Mongolia. She had hoped to escape Europe but now she's being dragged back by an old friend to play Quidditch professionally. On her good days Jamie is grumpy and sarcasic. On her bad days she is flat out hostile. She's a bit of a tough nut to crack but more than anything she just needs someone to put aside the bad things and really get to know her.
Mira - At only 19 she's the already very pregant (as in about to pop any day) fiancee of Elijah Krum. She's best friends with Athena but isn't planning on getting caught in the same domestic lifestyle as her friend. She's unemployed, restulting in her spending too much time locked up in the house. She's quite a lonely person and is looking for some sort of purpose, though she has a habit of pushing people away. Mira is very strong willed and vain, but in no way an evil person.
Maximus - his PB is Benedict Cumberbatch so Star Trek buddies. But anyway, Max works in the Department of Muggle Relations and is in love with his job. He's just gone though some life changes by moving in with a stranger and her neice (not to mention their pet's). Max is extremely down to Earth and soft spoken. He's extremely intelligent and hates any sort of confrontation (though he is loyal enough to fight for his friends). A true ex Hufflepuff.
Robin - Age 20, former Durmstrang student. Even though he comes from a wealthy family he spends most of his time lurking in sketchy Dublin pubs and getting into trouble. He's arrogant and lazy but when you get to know him it's undeniable that he's a truly nice guy. He's a Death Eater, but more for the title than anything, so he wouldn't cause the Ministry any real trouble or be on lists.
Yup. I'm probably forgetting someone but that's all for now. But I've also got Gisele Delacour (Helenes little sister) who he might run into if they keep going on dates. Haha.
