Garreth is a jock, Leander is a nerd. Garreth likes watching Leander study, admiring what he looks like when he concentrates. Leander likes watching Garreth play Quidditch. Both get butterflies when they do.
Garreth is on the Gryffindor Quidditch team and Leander can barely get on a broom the right way. Garreth spends a lot of his free time teaching Leander how to fly, and is unendingly patient with him even when he gets frustrated.
Leander is the only person Garreth won't test his experimental potions on until he's sure there's no negative effects. Leander still wants to try them.
Leander can be prone to moods and sulking, but Garreth always knows how to cheer him up (it's usually chocolate or playing with his hair).
Leander loves to lie on top of Garreth and fall asleep - Garreth is the only person tall enough/broad enough to handle his height and he feels comfortable sleeping in his arms.
Garreth is usually the one getting the pair into trouble, and Leander is usually the one who gets them out of it.
They have a friendly rivalry with the Slytherins, but Garreth is always on watch to make sure things don't go too far. If they do, the Slytherins might find their drinks spiked with one of his experimental brews.
Leander fell for Garreth way back in second year, but it wasn't until fourth year that he admitted it because he accidentally revealed that his Amortentia smelled like Garreth's hair.
Garreth loves being the little spoon.
Garreth's quite popular and charismatic, but Leander has the social grace of a frog. Garreth makes sure Leander is always included in conversations and won't let anyone talk over him.
Their first kiss was after the last Quidditch match of fourth year, when Gryffindor won because Garreth whacked a bludger into Ravenclaw's seeker and took them out completely. In the middle of a cheering crowd, emboldened by victory, Garreth found his tall and lanky best friend and made the first move.

While Garreth is quite versatile, Leander is a bottom through and through. Whether this is down to his natural shyness and insecurities, he’s happiest when he’s taken, as opposed to doing the taking himself.
I HC Garreth as being happily bi and very comfortable with his sexuality, but Leander is 100% into men, and still very conflicted about it due to the 1800’s stance on homosexuality, despite the wizarding world being much more accepting. It took a long time for him to come to terms with his feelings for Garreth, and even longer to be comfortable doing anything other than sharing a kiss, even when they were as secretive as possible.
Despite (or perhaps due to) Leander’s repression when it comes to sex, when he finally gets comfortable with the idea and confident that he’s not going to be found out, he becomes a bit of a sex-crazed maniac. He wants it all the time, and Garreth, despite his stamina and willingness to indulge his slutty bf, can’t always keep up.
Both of them love to kiss the other constantly during the act, meaning that they've both got bruised and sore lips for a little while afterwards, but both consider it a small price to pay for the enjoyment they get from each other.
Leander is wildly insecure about the way he looks, believing himself to be too lanky and pale. Garreth goes above and beyond to try and reassure him, praising him near constantly when they’re intimate, leading to Leander developing a bit of a praise kink.
Garreth is very much open to anything in the bedroom – he’ll try anything once and with a lot of enthusiasm. If he wants to try something that’s beyond vanilla, he’ll do his best to learn about it beforehand so he knows what he’s doing. He does have a habit of losing himself in the moment, though.
When the pair become a bit more comfortable with their relationship, Garreth takes to brewing experimental potions to enhance his performance. This led to a rather amusing escapade in which he overbrewed his own version of ‘the little blue potion’ leading to a six-hour long session that left Leander walking with a limp for a couple of days. He didn’t mind.
Leander has a rare condition known as ‘hyperspermia’ which basically means he produces a LOT more cum than the average guy. Bit of a shock for Garreth the first time they were intimate, and he was strutting around like a peacock for days afterwards because he was so proud of himself. When he realised it was going to be buckets every time, he got even more invested.
(Also side note I HC our darling Omi has the same condition but that’s just bc I think it’s sexy as fuck)
By the time our favourite HL MLM couple reached their seventh year, Leander had come out of his shell enough to become more adventurous with their intimacy. This led to an incident in the showers after a Gryffindor victory on the quidditch pitch, when a couple of team members came back unexpectedly to pick up their brooms, and the pair were forced to disillusion themselves in the hope that Garreth wouldn’t be found balls deep in Leander. No one mentioned anything about it, but to this day, students still whisper that the Gryffindor quidditch team’s showers are haunted.
