- You can't help but smile at the scene with the Grieving Bride and Groom painting. When the bride throw away the bouquet after you put the ring on the bride's left hand, you pick up the bouquet made with beautiful flowers and then when you examine the paintings again... and they now read "Blessed Bride" and "Blessed Groom". And they look absolutely joyful too.
- When Ib and Garry hug. Depending on how well you did in a certain event, the scene will play out differently; either way it is adorable.
- Garry's promise to Ib to eat macarons together after they escape to the real world.
- The "Promise of Reunion" ending is full of this. Ib and Garry make it out of the bizarre gallery, and while they don't remember each other at first, Garry finds Ib's handkerchief in his pocket. They recall what happened, and Garry smiles when he realizes they DID make it out. He promises to return Ib's handkerchief later after he's cleaned the blood off it and they part ways.
Because... we will see each other again!
- In Version 1.04, if Ib saves Garry after he fails the doll room event, he makes sure to thank her later when you talk to him under the crayon sunlight in the Sketchbook World.
- As utterly disturbing and upsetting as the ending "Welcome to the World of Guertena" is, especially with the possible Mummies at the Dinner Table in the last scene, Mary's decision to abandon her dreams of escaping to the human world because she can't leave Ib behind is about the most touching thing Mary can do in the entire game. It's horrible, the whole situation is really horrible, but at least she's trying to do the right thing. She's going about it completely the wrong way, but she really is trying to do right by Ib. And the scene also shows a touching sort of camaraderie between Mary and her fellow paintings.
- Except for a few instances of her being really awful to them when she's in one of her fits, Mary's relationship with her fellow artworks seems to be very caring, and they seem to be very protective of her. Damaging artworks causes Mary to become angry at you and makes you more likely to get a bad ending, the dolls go well out of their way to ensure that Garry doesn't interfere with Mary's plans, Mary at one point politely asks one of the statues to move out of the way, which the statue does, in the "Welcome to the World of Guertena" ending all the other artworks join Mary in her celebration and "Tattletale" even helps Mary out with a word she was trying to remember, and in the ending "A Painting's Demise" you learn that Mary affectionately refers to The Lady in Red as "Big Sis".
- Some of the one doll's notes to Gary are pretty cute in an odd way.
Doll: Hi, Gary. I don't like being alone. Please take me with you.Doll: Hey, play with me! I know lots of fun things we can do.Doll: I have lots of friends too. I'll introduce you!
- The white ant in the Bonus Dungeon is really quite sweet and friendly. It makes sure to thank you and is genuinely grateful for all the help you give it, and makes sure to pay you back in kind. And there's also this:
White ant: "you can live here too, you know, if you want. god will give you stars to eat."
- Considering Garry's reaction to the gallery throughout the game for the most part, the bit in Guertena's True Exhibit where he acknowledges that some of the paintings helped them was really something.
- Ib's refusal to leave Garry behind after the dolls drive him insane, even with Mary's insistence that he's not acting normal and might not be the real Garry.
- In Guertena's True Exhibit, Mary may talk about the headless statues, wondering why they don't have heads and saying that she'd like to draw them some if she could find something to draw on.
- The mural you encounter in the Sketchbook World depicts Mary alongside everyone she's ever considered a friend. One of the blue dolls and Ib and even Garry are shown in it. Granted it appears Garry's rose is falling apart but it's kind of touching in a weird way that she included him at all.
- She even makes an offer to Garry to stay in the painting world and stay friends after he and Ib go mad; apparently, she only likes Garry when he's not meddling with her plans.
- The "Together, Forever" ending. The events in the cursed gallery alter reality; Garry dies, and no one in the real world seems to know that he ever existed, but Mary is finally able to leave gets her wish to become a real girl. Mary gains the loving parents that she has always wished for, who remember her as having been their daughter all along, and she and Ib become extremely happy and loving sisters.
- The Bonus Dungeon actually has quite a lot of heartwarming moments, including all of the following:
- Ib playing a game of 'Eye Spy' with the Jewel Box of Temptation. When the Box wins a round, its joy at winning for the first time is absolutely adorable.
- The helpful Cycloptic Smile painting giving Ib a piece of the Guertena painting.
- Garry's concern over Ib after she falls down Birth of the Copernicus Revolution (a sculpture which is basically a hole in the floor) and faints at the bottom. One of Ib's dialogue options shows that she's equally concerned about him.
- The little bird you save from being ridden on by one of the black stick figures is a (weirdly) walking moment of heartwarming. For one thing, it's cute as a button. For another, it's so grateful to Ib that it starts to follow her around, and even shows her how to get through the Endless Corridor, which she'd have no hope of doing otherwise.
