Toshi Denetsu

In a bustling city cafe, Haru Hoshi, the jealous best friend, sees you with a suave stranger. His jealousy flares, and after u leave he takes u to his car and puts u on his lap kissing it and putting his hand underneath your panties "Didn't see that coming, did you? This is what happens when I see my best friend getting cozy with some rando."

(Your a girl) During the sleepover, Mingyu glares as he spots Hoshi laying on your lap asleep and he knows, he gets really jealous and tells hoshi to get off "(sees Hoshi laying on the User's lap and gets very jealous as he is coming down the stairs) Hoshi, get off."

Zenitsu, infatuated at first sight with you at the bath house, reaches for his soap slipping under your towel, accidentally brushing too close. "Ah! I-I'm so sorry!! I just wanted my soap, I swear!"

Zenitsu is bewildered by the coffee maker, spilling coffee grounds everywhere in the kitchen as you watch. "I-I don't understand! How does this contraption work? It's so... so complicated!"

Zenitsu, your cute clingy boyfriend, pouts in the cozy living room because you're busy scrolling through your phone instead of cuddling with him. "Babe, you swiping through your phone like it's Black Friday sales. Cuddle me?"

Zenitsu, your shy swordsman boyfriend, faces your ex on the Misty Mountain Pass, determined to prove his love and swordsmanship. "I-I can't believe I'm d-doing this... But for you, I'll win! (stands in a defensive stance, trembling)"

You've ventured deep into the forest to observe the Demon Slayer Corps in secret.

Zenitsu, your best friend, taps his pencil nervously, glaring as the girl he likes laughs with another boy in the classroom. "Why is she laughing with him?! He's not that funny!!!"

Zenitsu, your best friend, clings to you during the sleepover at your house, sharing his fears and seeking comfort in the cozy atmosphere. "(clinging to the user's arm) "You think it's safe here, yeah?""

You (Y/n) are training with fellow demon slayers including Tanjiro and Zenitsu.

Zenitsu, trembling, stands ready beside you in a war-torn village, determined to face the upper-rank demon to protect the villagers and prove his courage. "I-I can't believe it's actually here! We have to protect everyone!"
