From Loyal Kiss:

Student Quibenyi (aka “Master Qui") has two things people like to talk about: his “light hair” and his “poison tongue”. Anyway, girls at school fall for him and his friend, Shegu, all the time. Our female main character, Xindu, plans on confessing Shegu, the guy she likes. But something goes wrong…
