Skimmed through chapter 20 (kind of in a hurry):
Washio and Asakura have a heart-to-heart talk. Washio asks Asakura how he'd feel if someone of the same gender liked him, and upon getting a positive response, she reveals her love for Kotooka to him as well. Washio confides a bit in him regarding their current situation, and they get into a discussion about how they view themselves (Washio thinks she is uncool and feels insecure as she thinks back to the fight with Kotooka in the previous chapter).
At this point, Asakura talks about how he used to dislike himself through elementary school (closed off from others and rude), until one day, he met Tsukasa at a summer festival. We see here this is why he likes her - because she inspired him to become a better version of himself. From there, he discovers the appeal of heroes and becomes more like them. He's more open with others and his friendliness attracts the attention of other people. In the end, he is happy with where he is now because he can finally say that he likes himself. Asakura reassures Washio that she is fine the way she is and doesn't need to change. Washio is then determined to make up with Kotooka, partially for Tsukasa's sake.
Tsukasa and Subaru die (not literally) of loneliness together on the couch. Tsukasa's friends quarreled in the last chapter, so all she can do is hope that they make up. Meanwhile, it seems that Subaru might've had an argument with Asakura several chapters back (I didn't read anything before 19, so I'm unsure) and he has a nightmare of Asakura giving him the cold shoulder. As he gets up, he wonders why he's thinking about him.
The chapter ends with Subaru posing as Tsukasa during her daily morning jogs (a routine she discontinued in one of the earlier translated chapters), so Asakura is shocked at her appearance. "Tsukasa" tells Asakura that Subaru has a message for him (or rather, "she" literally says "I've come here in the place of Subaru.")
