Seiya x Reader Scenarios

How I taught him to bake two cakes

This is scenario and the one following after are requests from @MylaByers.

After Seika reunited with her younger brother, she decided to live in Athens, since that was her new home after she left the orphanage and lost her memories. A year went by and when it was March, Seiya came to me with a big favour. Bowing his head with his palms pressed together, he begged "Please, help me bake a birthday cake for my big sister!"

I just came back from school and found Seiya waiting in my home, my family having let him enter to wait in my room. Because of experience, I was quite hesitant about that request and asked "How much time do we have left until her birthday?"

"Two weeks. Her birthday is on the 18th... That and... Can we maybe make it two cakes? It's also Marin-san's birthday." Nervous, he scratched the back of his head and didn't dare look me in the eyes.

I chuckled through my nose and nudged him "Did you really think I would deny that request?"

Relieved, Seiya gave me a tight hug and thanked me a thousand times. But really, how could I deny that request when I know how much he missed his dear sister and how much of a sister figure Marin has become over the years?

After I asked him what kind of cakes Seika and Marin would like, I told him that we would practise the next day. After school, Seiya picked me up and together we bought all the ingredients needed. Stretching my arms and back, I held two notes with recipes I looked up online. As I put the apron on, I started to explain "We will start with mosaiko cake for your big sister first, since it is the quickest one to make."

I could have baked the cakes for him but I was pretty sure that he wanted to bake the cakes himself or else it wouldn't be a sincere gift. So, I decided to teach the old-fashioned way: Slap his hand every time he is about to mess up and bombard him with instructions until there is absolutely no way he messes up.

But if it was so easy, we wouldn't start practising two weeks in advance...

The first day we tried to make the mosaiko cake for Seika, I had to change my teaching approach. The next day I let Seiya sit next to me to see how the cake is properly done and he would try to do it himself the day after. Of course Seiya didn't know the techniques to make meringue and he struggled really hard to separate the whites from the yolk, which is why most of his attempts failed. At first he tried to balance the yolk with the egg shells (if he didn't destroy them with one smash) but seeing how he never manages to do it correctly, I suggested using his hands instead. Of course it was way easier to do it like that but Seiya simply leaked the delicate approach, after all his strength lied in brute strength. Another problem were the cookies and walnuts he would try to fry in butter. I swear, I stood with a fire extinguisher everytime Seiya was working on the stove, fearing that he would mess up somehow and start a kitchen fire.

I was almost tempted to ask Hyoga to protect us...

Anyway, we spent almost a week practising the mosaiko recipe until we moved on to the red velvet cake for Marin.

And, oh boy...

That was another level of cake.

We chose a two layered red velvet cake variation with cream cheese frosting. The mosaiko cake didn't need to be baked, so working with the oven became a new dread, especially because Seiya had no idea how to operate it at first. Of course, I wasn't crazy enough to let him experiment with it, since it was the oven that my family and I used. So, I showed him how to use it the first time and I would always slap his wrist when he set the temperature too hot or for too long. And because the cake was layered, he had to prepare two batches of sponge cake. And hold on behold, he would either make not enough sponge cake or too much, which is why we would end with three layers.
