Thanks for the new chapter!
I was surprised the mangaka did not show the game but I wasn't surprised they lost, but I supposed Seiei totally crushed them because they recognized their potential, and they wanted to eliminate future rivals while they are still budding - not necessarily because they are mocking them (but partly so, so they can show how much the gap is between them).
But still, Souta is still a chad so far. I am really liking his 'stop being so much of a simp and just play and work hard' attitude in life. While the romcom element is in the back-burner, I somehow like this pace better, than it being forced (and potentially making it look like a 'BokuYaba look-alike').
