Summary
Rean stops by at Booze Man's place and approaches Fushi directly. She asks what his favorite food, to which Gugu replies that he like anything he makes for him but Fushi replies that he likes fruit. Rean then asks Fushi to say her name, and Fushi says her name. Gugu appears between them and now asks Fushi to say his name instead. After saying Gugu's name, Gugu drags Fushi at the counter saying he's being a nuisance to the customers. Flustered, Rean suggests that she can walk with him, then he won't be a nuisance. Gugu replies that Fushi is not capable, that he cannot even take his own clothes or capable of proper speech, and that he needs education and no time to play around. Rean then offers that she could teach Fushi how to speak and how to take off his clothes too.

Gugu is seen lying on a bed when he is approached by Booze Man telling wise words that "Man cannot live on alcohol alone." Flustered, Gugu gets up from the bed while Booze Man continues to give his word that "One can drink alcohol and thus enjoy the passage of time, but it will be insufficient to maintain his lifestyle." Gugu, confused, asks what he is saying to which Booze Man replies that it is a parallel. Booze Man says his last words of wisdom to Gugu and tells him to feel pain and be a proper human.

Gugu is seen outside the Booze Man's place doing exercises. While doing bar pull-up, he is approached by Fushi and asks what he is doing. Gugu responds that he is training and giving himself self-worth. Fushi tries to climbs up the monkey bar but Gugu stops him and orders him to go back and sleep.

The next day, Rean says that she wants to work at Booze Man's place. Booze Man asks if she is sure regarding her decision. Rean replies that she is sure and would like to make a request to live there and it won't cost commuting. Booze Man is delighted and that it would work out perfectly. Rean bids goodbye saying she will come back tomorrow.

At dinner, Gugu asks if it is okay to let Rean live there, Booze Man replies that it's fine since they have spare rooms and orders Fushi to not let Rean know about his ability. Fushi asks the reason. Booze Man replies that if she were to found Fushi's ability, it might scare her and will ruin more the store's reputation.

While cleaning up, Gugu asks Fushi is he can do anything else. Fushi replies that he doesn't know to which Gugu says that he is already sick of that answer. Fushi the proceeds to show him an object he can make from his body, a spear. Gugu asks if he can make a bowl but Fushi says he can't make it and doesn't know why. Gugu replies that he still has not seen Fushi how immortal he is so he gets a sharp knife and cuts on Fushi's arm. Fushi says it hurts and the wound starts to heal, he then is able to produce the same knife from his body.

Gugu then theorizes that he can make the object due to reacting to pain. He then grabs a torch and places it on Fushi's arm. Flustered, Fushi is still able to create the torch from before but without the fire. Fushi makes a sad face and Gugu tells him the reason why he is upset since he can't die and if he is upset about something, he needs to say it. Fushi says that he understands. Gugu tells Fushi to go to bed and turns off the lights. Fushi goes outside and turns into the wolf form, making way to a small alley and sleeps there.

The next day, Rean appears at the store and asks where Fushi is. Gugu replies that he is not sure since he has not seen him since morning and might be back by dinner. Gugu then asks Rean about her wound and Rean replies that it will take more time to disappear but the pickled garlic Gugu gave him was good.

While doing chores, Gugu asks Booze Man something to heal a wound but Booze Man replies that a three-month-old wound should be healed by now. Booze Man then says that he has something wound and asks Gugu to sit down. He inserts a tube insides Gugu's mask. The tube pumps out alcohol from Gugu to a container. Gugu then asks what Booze Man is doing and Booze Man says that it is refined alcohol and use it to spread on Rean's wound, He then proceeds to tell that he has always been interested what happens to alcohol stored inside a human body and reveals that Gugu has an extra organ. Gugu, furious, asks why would he do something like that. Booze Man replies that the experiment will help the field of science and he pursued it to satisfy his curiosity but reassures him that Gugu will not die. Shocked, by what the Booze Man says, Gugu runs off and says he's leaving the place. Fushi wakes up because of the commotion and goes back to sleep again.
