It's a very cute mini chapter but now I have a ton of questions about Ichitaka like what was his club? Why did he become a loner? What cause him to lose all self esteem?
Everyone here's talking abput how the chapter is innocent and wholesome (despite some people here making certain lines more awkward than intended).
Here I am curious as to who is the person who wanted to see Ouji's big brother (Ichitaka?). Is she Rin's older sister and it turns out Ichitaka had a cousin who crushed on him like Ouji does? Is it possible Ichitaka was more popular than he thinks he is? Does Himeno's older sister have a potential love rival (assuming she's interested in Ichitaka)?
The only answer we do have at the moment is for the question "Am I overthinking this?".
