My Sister Insists on Marrying Me, and so Does Her Best Friend

[Multiple female protagonists + sister-brother love + pure sweetness without swords + happy enemies + no regrets + easy love] (My online dating girlfriend is my childhood sweetheart!) (The tutor is my sister's best friend!!) (The trolling game friend is the contrasting sister!!!)… "Which is the longest road you have walked?" Su Chun recalled it until she saw Gu Qingyu with a smirk on her face. "Well, there is no need to doubt it. The longest road I have traveled is this guy's routine." "Aren't you happy with this!? Come into the house with me." Gu Qingyu said with a half-smile. "How is that possible! We are a perfect match, one is willing to fight and the other is willing to suffer." Su Chun quickly begged for mercy. "Hmph, you know what's going on." (The introduction is too weak, so move on to the main text.) (Read the first four chapters. It doesn't look good if you hit me.)
