K-ON! episode #13
During the next meeting in the clubroom, Yui complains about being unable to play guitar with cold hands. She suggests playing with gloves, but she can't play well with them, just as expected by Mio Akiyama and Ritsu Tainaka. Yui and Mio notice that Ritsu suddenly looks vacantly and ask her if something is wrong, but Ritsu negates this and changes the subject.
Yui suggests eating nabe at her place the mext sunday together, but everybody has to refuse because they are already busy. Tsumugi Kotobuki says she already has a prior engagement while Azusa Nakano can't leave her home that day. Ritsu promised her younger brother Satoshi Tainaka to watch a movie with him and Mio wanted to come up with new lyrics for the band since Ritsu and Yui distract her too much anytime. Yui has to accept that everybody is busy and decides to just have the hot pot with her sister Ui Hirasawa and her guitar instead.
On their way home, Tsumugi leaves them earlier than usual and heads towards a near restaurant. After Yui and Azusa left Mio and Ritsu, Azusa says she needs to buy some toys and left Yui too. Meanwhile, Mio notices Ritsu appears to be vacantly again, but she avoids the questions once again.
The next sunday morning, Ritsu looks for the mail and appears to be looking for something else inside the mail box too. At home, Azusa is in a cat's company. She thinks back how Jun Suzuki begged her to take care of it for the weekend since Jun's grandmother is unable to do it because she fell sick. Azusa agreed, but is still nervous around the cat.
In the meantime, Tsumugi starts a part-time job at a fast-food restaurant under the attendance of her coworker Hitomi Hoshino and Mio sits inside a train listening to her band's song "Fuwa Fuwa Time".
While Yui is still sleeping, Ritsu fetches a paper at home and reads it. She thinks about it to be a love letter. Her brother pulls her out of her reverie and she prepares to go to the cinema with him. In the meantime, Azusa is unsure about how to entertain the cat, but she eventually sits down on her legs. Azusa, becoming fond of her, names her "Azu-nyan 2", as an allusion to her own nickname.
Meanwhile, Tsumugi learns fast in her new job, much to her joy. Mio finally reaches the seashore she wanted to visit to be alone in order to be able to come up with new lyrics. In the meantime, Yui and Ui are shopping for the hot pot and Yui tries to come up with new recipes.
Mio quickly notices she can't come up with any lyrics and regrets not being with Yui at the time. Having watched the movie, Ritsu and Satoshi travel back home when a friend of Satoshi shows up. The two head out to visit another friend and Ritsu is left behind alone.
At work, Tsumugi makes a mistake and runs into Hitomi, pouring her with coke, much to her shame. At Azusa's home, she notices that Jun's cat starts coughing up hairballs, something she never saw before, hence she starts to panic. It is then that Yui sends to every band member mails with her new hop pot receipts, confusing everybody. Azusa calls Yui asking for help. When Ui and Yui visit her at home, she learns that it's normal for cats to cough up hairballs every now and then.
Everybody meets at the restaurant Mugi is working at afterwards. Ritsu then found out that the love letter is in fact just some lyrics Mio came up with, much to her anger.
Back at school, they notice how warm Mugi's hands are and Yui once again thanks them for being part of the club too. In the end, they encourage themselves again to perform at Budōkan one day.
- The lyrics Mio wrote eventually became the lyrics for Ho-Kago Tea Time's song "Fuyu no Hi", which shares its name with the episode.
