The days of hanging out at Hogwarts

Description

My dear grandpa is actually a werewolf, the truth behind the Philosopher's Stone, and the back-up man behind the four founders.
None of this prevents Loren from being a bastard, having fun with Seamus, exchanging experiences with the twins, and explaining the weirdness of Quidditch...
This is a story about hanging out at Hogwarts.

The first transfiguration lesson
Loren: Look at that cat above, it looks so easy to touch.
Hermione: Heartbeat, in short, it is heartbeat.
Five minutes later
Hermione: Loren! ! !
(PS: The three little ones are the same age, they don’t follow the main line of the original work, they don’t have a system, and they try their best not to be OOC.)
