4

Saki admits she feels inferior to Nagisa and it annoys her that Naoya does everything without asking for anything in return. Surprisingly, Nagisa agrees that Naoya does too much for them. Naoya realizes by taking all the responsibility, he was actually being selfish. With Saki back home, Naoya passes out from his three days accumulated exhaustion. Saki and Nagisa debate how exactly they will become equals and realize they both like gaming. Nagisa is terrible at gaming and Saki feels better knowing there is something she is better at and they become friends. While watching another player called Milika streaming her games online, Naoya sees a school uniform in her thumbnail and realizes Milika attends their school. During lunch in the gym storage, Saki forgets to lock the window and another girl, Rika Hoshizaki, climbs in. Naoya panics and accidentally admits everything, amusing Rika who teases them about revealing their secret, until Nagisa recognizes her as Milika, causing Rika to also panic. As everyone now has secrets they do not want revealed, they all agree to keep quiet. Realizing they are actually decent people despite their unusual relationship, Rika decides she wants to join them as Naoya's third girlfriend. (Source: Wikipedia)
