Since you're asking! I'm a big fan of meek-reserved switching to a more extroverted confidence as the BE happens. Method I would prefer it to be magic. Maybe it just happens to her via a wish or something? Drugs has its perks but it being magic makes it more unique to her.
Side characters for this stuff I always like when there's more females for envy purposes. Like, she outgrows her current year classmates, bust best friend she's been borrowing bras from, then the upper years, then her teacher, then her mother.
Scenario wise I loove when guys who never gave the MC a second glance are drooling over her. Love the scenario where there's the lusted after upper classman whos unavailable [already has gf] but once the MCs bust grows to surpass his current GF she breaks him and steals him from her. Before that she could engage in tittyfucks with guys so its known she's available and DTF.
Also scenarios: shes constantly spilling out of her tops or bursting buttons as they slowly steadily grow. Bra breaking. Especially in front of boys by like, inhaling deeply. Going without a bra due to costs and enjoying her massive tits and firm nipples filling her shirts.Eventually having her switching to corsets after destroying even the largest bras.
She goes to the gym to start exercising her back muscles more to support her weighty chest and wear tight overflowing sports bras. Maybe the guy shes after also goes to the gym.
Also love the idea of lactation once they hit a great size, milk production starts slow but speeds up to the point where shes draining out half a gallon per tit daily. And the magic makes her milk special: its delicious, mildly addictive and has a slight aphrodisiac effect so any guy whos drinking from her ends up fucking after.
Sorry if this is a bit much but I love slow growth BE as much as rapid.
