basically, the chapter start with sudden childhood trope. and then scarlet happy to be able to reunite again. and then our mc come in and groping her all over, at first i shocked that scarlet let him to do that, cuz we don't see scarlet being in that kind of realtionship with him yet. but turn out she was into it too, she wanted to see how the childhood friend reaction when she was being groped. basically, the two of them was teasing this poor naive brat. nothing serious. and then the mc let scarlett to have a reunion with her childhood friend. and the childhood friend proposing to her to come to his party thinking that scarlett was being taken advantage by our mc. basically a naive brat from ntr genre trying to he a late hero. and scarlett was actually taking it into consideration too, she said she want to talk it over with her other party, so she want some time to thinking it over. and then scarlett want to talk about it with our mc in his room. the childhood friend see the two of them going to mc room. he think what she said before about "wanted to talk it over with her party and want some time for it" was actually about this. and then the brat fantasizing about her being taken advantage again because if she want to leave the party she need to repay her debt with her body.
next, scarlett said "what do you think about if i want to leave the party?" to mc. and then mc said he would never let her go. and brush it with "remember about the potion you drink before? you know how much it cost for one. and you drank a whole lot for it. i ain't let you go before you repaid all of that. prepare to work your bone for it". scarlett reminscing about all of those event in the dungeon before, she think that a mage was supposed to be cold, to use all of their member party in the frontline to be their meat shield while they charging up mana and spell magic, a mage should never ever be close to the frontline, as long as the mage in the party is stay alive, the dangerous moment could be flipped anytime. and then in the end, scarlett said "because i don't want to have debt, i will repay it, right here, right now" and then the chapter end
