The Exterior of Humans and 'Monsters' (人間と“怪物”の外側, Ningen to “Kaibutsu” no Sotogawa) is the 20th chapter of the To Your Eternity manga.

Summary
After finding Gugu and Fushi, Rean tries to get Gugu to come back to Booze Man's place. Gugu then says that he won't come back since he became a victim. Rean then tells Gugu that the old man repented for what he did and will take out the alcohol inside his body for free. Shocked by the news, Gugu still asks if it's free, and Rean reassures him. Gugu who is still suspicious why does everyone want him to come back. Rean remembering that the Booze Man and Pioran don't like her cooking also does not want to be in charge of it, bluntly says to Gugu that they need him and they love him.

Gugu then asks if Rean also misses him and Rean replies that he misses him, Gugu blushes but insists that he won't go back since he threw away his mask, throwing his humanity as well. Confused, Rean asks if the mask was only a gag for the customers. Gugu reveals the truth that the mask he used is for him to hide the injuries on his face. Rean then asks if he's still hiding it and begins to see Gugu's injuries by snatching the blanket from him.

Gugu hides behind a tree while calling Rean ruthless. Rean then asks why Gugu is still hiding behind the tree and who cares about his face. Gugu then replies that he doesn't want to be seen. Fushi then interrupts that Gugu is showing his face before. Rean then asks if Gugu will stop hiding if he has the mask and proceeds to ask where he left it so she could get it. Fushi then approaches Gugu and tells him that his heart looks always hurt whenever he talks to Rean and suddenly leaves to go find Gugu's mask leaving Gugu and Rean alone.

After Fushi leaves, Rean offers to show his wound to Gugu and tells him that it was a pretty bad wound and maybe Gugu realizes that his wound isn't bad enough to hide it. Rean then shows the wound to her arm which appears to be a small scratch. Gugu then says that it's not horrible and it's a small scratch and nothing compare to his injury and that there's a limit to over-acting. Flustered, Rean sulks and tells Gugu that it's the same her parents tell her and that her parents treat her like a pet and make things go their way. Gugu then tells Rean that he has nice parents even though they're foolish. Rean then blames that she got the would because she was born from that house someone pushed her from behind who might be someone who has a grudge to his father. Gugu then tells Rean that she is wrong and calls her stupid. Rean then gets up and looks to Gugu who is trembling.

After seeing Gugu trembling, Rean asks the reason Gugu has an injury on his face. Gugu says that he won't tell her or she'll hate him. Rean asks then if he likes her and Gugu responds again that he won't tell her or she'll hate him. Gugu says that he is a monster and tells Rean that that's all she needs to know. Rean then gives Gugu a mask which is a legendary mask according to Booze Man. After getting up, Rean tells Gugu that she doesn't care whether Gugu is a monster or human and that either way, Gugu is the way he is. Rean then tells Gugu that she wants to know him better even if he needs a mask and walks forward. Rean looks back to find Gugu wearing the mask she gave. Both of them didn't wait for Fushi and leave.
