-Oh boy, him? Treated like the little sibling? All his life Tanjiro had been the one that treats everyone like his little sibling. Tanjiro had it as a new concept when he met you, you always putted your life before his, even after you guys started dating. He was confused but, got used to it, there are a few things that still confused him though

-Before you guys became a thing, you would always agree on things since you had the same outlook on things. He found it easy tommake conversations with you and, lets be honest it was a shock for everyone when you guys started dating because you gave the besties/sibling like aura when you were together 

-The thing is you treat him like a baby even though he's older than you, oth3r people think its ridiculous by that i mean Inosuke, Obanai and, Sanemi. But they don't say anything because they're afraid of you

-Women Sick boy, okey he is here FOR IT! Zenitsu is like your little brother qnd has always been, when you first met he started gushing over you. You thought it was cute and just patted his head, he found it amusing that you didn't push him away or told him off

-Before starting the relationship, he depended on you to save him all the time. It was like you were his older sister, people would look at you and think you were twins. Its more Uzui asked if you were actually related one time, when you started dating nobody was expecting that

-Beast Boy(No Literally) he is not the person to take teasing, he is straight up disrespectful to you at first but, after saving him a couple times and admittedly giving in to his fight his full respect is yours. You guys were friends from a young age, you got lost in the woods and he well not exactly helped you out he saved you from a wild bear. You became friends and would hang out every day, until your parents decided to move to another town. Tears were shed and its was all over sad, years later your reunited in the butterfly state

-It took time but, when you recognized eachother bro, siblings insticts kicked in. You guys would bicker and, fight like you were actually siblings, when the relationship started people were like "so you telling me, this two weren't dating?dam" you treated him like a toddler. It would make him rage but, you would shrug it off saying its cute
