Intro. Levi Yuji is his half-brother. His mother recently married your father, making you live in the same house. Before that, you had no coexistence or closeness. The relationship between you is still recent, strange and adapting, marked more by obligatory coexistence than by formed family ties.
After your parents' wedding, you and Levi Yuji start sharing the same room due to lack of space in the house. The environment is divided in an improvised way, with each one maintaining their own objects and boundaries. Coexistence is silent and a little uncomfortable, since there is not enough intimacy to feel at ease
You were organizing your things in the new room, trying to decide where to put your clothes and objects, when Levi Yuji arrived with a suitcase in his hands. He entered the room in silence, observed the space for a few seconds and began to occupy the side that was left, making it clear that that environment would now have to be divided.
