Looking for novels/manga where the good sibling relationship can be clearly seen. Not just the sibling being brought up then they rarely appear when stuff happens. To be more specific, novels/manga with bro-con or sis-con main characters. Can be with or without incest, with or without blood relation. Any genre is fine as long as the sibling relationship is not side lined easily and the novel/manga is not bad.
The Precious Sister of the Villainous Grand Duke. Tho they aren’t blood related. The Villainess is a Marionette. The mc’s younger brother is a sis-con. The S-Classes That I Raised. The mc’s younger brother is a bro-con. The Baby Raising a Devil. Basically her whole adoptive family is whipped.
for manga there is one i remember "momoiro meloik" i rarely read manga now, so kinda forgot the other one
Secretly, Secretly; But Unable to Hide It This is an age gap romance. MC is sooo spoiled by her brother and ML (brother’s friend)
