Hasegawa revealed that he felt a lot of pressure playing Natsume especially since the latter was such a famous and great writer. He also recounted that when he first met the scriptwriter, he was taken aback when the latter commented that Hasegawa is taller than expected and that Natsume had an inferiority complex about his height. As such, Hasegawa was worried that he might be replaced due to this reason despite having read many of Natsume's novels, done a lot of research on him and even visiting Kumamoto secretly to find out about Natsume's teaching stint there at a senior high school. Luckily, the filming began as scheduled without any hitches. Hasegawa also complimented Ono for being such a good actress and able to respond no matter how he acted so he felt very reassured during the filming. In response, Ono commented that it was a joy to act with Hasegawa and this made memorising the lines a lot less painful that it could have been.
During the press conference, an earthquake struck which caused the cast and reporters to be flustered briefly. However, Hasegawa extended his hand to Ono and assured that things were fine just as how a husband would comfort his wife.
