Tomo's crush on Junichiro isn't cute or funny because she's a tomboy, it's devastating because she's been invisible to him her whole life, and no amount of femininity will change that until he actually looks. The show knows the real joke isn't her failing to get his attention; it's that she's been right there the whole time. By the end, you're not laughing at her anymore, you're watching someone fight to be seen by the person who matters most, and it lands with surprising weight for a comedy about a girl who punches things.
Tomo has spent years as the tomboyish friend Junichiro takes for granted, roughhousing with him every morning and hanging out like they always have. The problem: she's completely in love with him, and he remains utterly oblivious. She tries everything to get his attention, dressing up, showing off her softer side, being obvious about her feelings. Nothing lands. Junichiro treats her exactly as he did in elementary school, cracking jokes and dodging her attempts at romance with the ease of someone who genuinely has no idea what's happening. This is a comedy about the specific torture of unrequited love from someone who sees you as just another friend. Tomo keeps trying different angles, her friends keep offering advice, and Junichiro keeps missing every signal entirely. The show finds humor in how dense one person can actually be, and in Tomo's increasingly desperate attempts to bridge the gap between who he thinks she is and who she actually wants to be for him. It's lighthearted and frustrating in equal measure.
