His brothers seem to have forgotten he even existed he felt lonely Osomatsu had them always say yes because they were scared of what would happen if they said no so not even Karamatsu came to save the day and get him angry or annoyed and jyushimatsu didn't even ask him to play baseball like they usually would and choromatsu and todomatsu never even bothered in the beginning to interact with him so what about the eldest osomatsu i guess he told the others to ignore ichimatsu since he never interacted with them so now when it was time to sleep only five people could sleep on the futon when it was dinner only 5 dinner plates were set on the table so I guess his only friend was his cat.
