Hi guys, I’ve been trying to find this manga about the seme being short and pretends to be kind and cute but is actually quite sadistic. Uke accidentally discovered it and the seme started harassing him. When they came back from summer holiday, the seme had a growth spurt. That’s basically what I remember from the main story but there was a spin off about the seme’s childhood friend who looked burly and scary but is actually very innocent and childish. The semes brother has been lusting over this boy for so long, the semes brother had long hair and works as a hairdresser. Please help me
