Jearim was Yuri's first but what he means in there he didn't know how to act in realtionship so he asked Yuri's friend Dunno and try to do even some crossdress for Yuri. Did you read Never Understand? This is webtoon continuation of Never understand.
when jaerim said he's been in the same position as ayeon, did he mean yuri too already had a lot of sexperience like woori? or was jaerim yuri's first?
