Kageki Shojo!!

The episode focuses on Kaoru Hoshino's summer before getting accepted to Kouka School. Everyone at school considered her weird for using an umbrella (to keep herself from getting a tan) when most high school girls don't. She also was under pressure because she is being compared to her grandmother and mother, both former Kouka actresses. But because of this pressure, she got to know a high school boy named Rikuto Tsuji, the brother of a famous baseball player. Them being alike in situation led them to hanging out together, even to the point of becoming a couple, but broke up after a clash of beliefs--Rikuto, doubting his chances of success with his team, thought his getting into baseball was because of the pressure to be like his brother; and Kaoru, on the other hand, wanted to be like her grandmother and mother. She left the fireworks display they attended in tears, tinged with her envy of a normal teenager that she's been shrugging off for the sake of her ambition. She blocked him on her phone later, and never went back to that bus stop where they usually hang out. Rikuto's baseball team was in the running for the Koushien, and rose from being a benchwarmer to an actual starting player during his days with Kaoru. She was happy when she saw Rikuto hit that home run that sent his team to the Koushien. She knew later that they were eliminated early in the tournament. Fast forward to the start of second semester at Kouka School, Sarasa shows Kaoru an image of a bus stop on her phone. Kaoru notices that it is the actual bus stop where she and Rikuto first met. It had a note taped to its wall--from Rikuto, thanking her. He is still playing baseball when he posted the note. Smiling quietly, Kaoru agrees with Sarasa that it's romantic, promising herself that when she finally gets to walk across the silver bridge and he still plays baseball, she would reserve him a prime seat at the SS section of the theater...and probably even confess her feelings for him.
