it's tied to ch. 13, from where the plot starts moving, so it's double spoiler. Actually...
-Haru gets anxious bc Souta ain't coming under Kasuga bridge after 2 weeks and kind of hints she's actually falling for him. She decides to visit him at his school on Hidaka.
-She ends stalking him all the way to his house and witnesses how extremely poor he is after eavesdropping about his Gacha canisters' mounting side job. On her way she gets relieved he is doing well. While subtle, it's still relevant bc it shows Haru actually cares for him, setting another difference with Yuri.
-She gets more anxious after asking her mum about side jobs (内職) and getting a dreadful answer. "Nobody takes those jobs unless for something extremely important", Haru realizes Souta's little change holds a significant heavier value for him.
-Ch. 14 starts with her still reflecting over that. Haru ends up fearing he won't come under the bridge anymore after remembering what happened on this chapter, she also remembers the moment when he saved her from his classmates and thinks she had never asked his name (as of the most recent chapter, she calls him "24 yen").
Parallel to Haru's epiphanistic panels...
-At the end of ch. 12, Souta naively apologizes to Yuri, she forgives him.
-Bc of her being at Souta's side, bullies ain't picking on him bc they don't want to have her against them. Souta doesn't realize Haru stalked him all the way to his shack.
-As of Ch. 14, Yuri asks him out to go shopping and then going picnic at Osawa park on sunday. Souta gets nervous bc it's his first time he goes out with a girl, he compares Haru's company with Yuri's.
-Date happens, Souta confesses he had to lie to his mom, even though Yuri seems to enjoy that, he can't stop thinking about Haru, even though he swore not seeing her anymore 2 chapters before.
-At picnic, Yuri attempts to steal a kiss from him (as of stealing his lips' virginity) and Souta pushes her away after remembering Haru's indirect kiss from ch. 9, realizing she isn't a bad person after all. He lies to yuri saying he must go back to home, however, chapter ends hinting at him going back to Kasuga Bridge. Btw, it seems Yuri didn't buy his lie.
