The Sick Tanaka-kun. Tanaka doesn’t use his umbrella because it takes too much effort; resulting in him getting drenched multiple times trying to evolve immunity to rain or dodge raindrops like a ninja. Shiraishi offers to share her umbrella but is so nervous she increases the distance between them causing Tanaka to be drenched again and he finally catches a cold. Unable to speak Tanaka decides to use a notepad, but when he tries to tell Echizen to change her name to something that takes less effort to write she thinks he is asking her to marry either him or Ohta. The next day Echizen’s belief both Tanaka and Ohta want to marry her leaves her flustered and confused. She decides Tanaka’s family name sounds better, but when she sprains her ankle Ohta is tall enough to carry her like a princess, causing her to become attracted to him and panic, so he drops her on her head. She finally explains why she has been acting strangely and Tanaka realises she misunderstood his asking her to change her name. Echizen is furious she spent all day confused because of Tanaka’s laziness, but returns to being embarrassed when they decide to nickname her “Ecchan” as it is easier to say and write.
