Nope
Nah when asked the novel author confirmed that Kishiar is a 29-years-old virgin with only theorical knowledge and secondhand information from acquaintances
oh noice, where did the author confirm it?
Their first Q&A back in 2020: https://www.postype.com/@kysident/post/8668098
9. Q. 연애 경험이 풍부 (The one with more dating experience)
기타. 키시아르는 간접적 경험이 풍부합니다. (Neither. Kishiar has abundant indirect experience.)
It says "dating" and not "sex" per se, but Kishiar having 0 direct dating experience logically means he didn't try wooing people either.
ya’ll does the ml actually sleep/slept around??
