[Tsubaki Jushirou] Issho ga Ii Ne ｜ Better Together (Aimai Diary) [Nishimaru]

Under the title “Better Together,” a thick-browed older brother admits that his crush is “way younger” than he is, while his bashful sister tries—and conspicuously fails—to be prudish around him. A bathroom misunderstanding gives way to bedroom intimacy, with nervous laughter, teasing, and one sibling’s bravado steadily answering the other’s. The spare black-and-white artwork turns their domestic closeness into a playful but charged story of forbidden affection.
