He hopes to work at a major hospital where he can get more free time to spend with his wife Haruna and also specialize in his field of study. However, Ichito is also reluctant to add to shortage of doctors at the clinic and break his relationships with the patients.

Durin this time, he discovers a letter made out to him thanking him for the care he provided to her, even though he could not cure her sickness.
