in earlier chapters you could see a sneak peak of what it seems eunsan and the other guy (i forgot his name) doing something strange together back in the current chapters days
i kinda think eunsan prolly developed attraction towards ian and wanted to see if he could feel that way about other guys too ? this theory is a bit on the cliche side but im curious to know what transpired there too (tho not ready)
i'm not ready to see eunsan and that other guy jacking off together
