Thanks for the chapter!
Seems like this succubus is really innocent and kind hearted for a demon. Although if she went at warp speed from his sweet nothings whispered into her ear how did the owl get so far ahead? It's great MC was able to help Krunia get a job, room and board so could get back on her feet and earn her own happiness. Probably just as well Seruria shocked her with too much reality as his plate is probably filled with just the succubus at the moment. Also, Krunia needs some time to get her feet firmly on the ground to sort her feelings out rather than get into a relationship with him that might just be feelings of gratitude and owing him a debt that would turn into a mess. After she gets to know him better, along with his daily way of life with multiple women, can consider raising their relationship from friends to something else.
@The5thSeraph You sure about that? Manga is right and would suffer a lot before dying from drowning. Clothes would restrict movements and drag you down. Lungs would be burning up and crying out for air but breathing in water would just add a new burning sensation. Also, any family left behind will grieve, along with any friends didn't know had. Then there's the suffering in Hell until the Day of Judgement. Granted her life is a mess but MC was able to help her find a steady job, get some income, and get room and board. Also, he's right in saying that she can get back at that jerk who ran off by living well. If they ever meet again he'll likely be in a bind or on the run while she's got a good home, friends, and a steady job to rub in his face. Or better yet, taking him to court and having him locked up for a long time for stealing all her money so he can have a job on the chain gang, food and a roof over his head. Between the hard work and preserving his anal virginity from a giant, hairy Neanderthal he'll suffer much more than any curse she could give him and can visit him every now and then to watch him grow more and more haggard.
