Yumoto's problem was that he couldn't stay still.
From morning until evening and from evening until morning he moved, talked, laughed, jumped, never stopped, a real dynamo.
Gora, as his loving and devoted big brother, was used to it. He even cherished this personality, he loved seeing his brother full of energy. Seeing him healthy was what he desired the most.
However, the Defense Club was not as good as him to handle him. Wombat was the one struggling the most.
The poor alien had to put up with his violent hugs all day long. And, worst-case scenarios, if Yumoto had decided to make him wear all sorts of accessories, there was almost no chance for him to escape it.
Io and Ryuu could handle him, at least more or less, but his wild hugs and his endless energy often ended up tiring them too.
Atsushi knew quite well how to handle him. He calmed him down, answered his questions, managed to make him stop cuddling Wombat... Actually he looked almost like a mother. That was probably what the younger felt as he always listened to Atsushi and calmed down quickly when they were together. Even if that did not last.
The Student Council clearly avoided Yumoto. Especially Kinshirou, who was done with En's embarrassing remarks, so if the youngest began to ask questions he would never hear the end of his “almost” relationship with Atsushi.
The Beppu twins... Well, they barely noticed Yumoto's existence. Since they had gotten closer to Gora, he was the only one who mattered to them.
But there was someone who could calm down Yumoto.
Atsushi noticed it first.
He had asked En to go to the club room before him. A few minutes later, when Atsushi had been about to open the door, he had noticed the lack of noise, which was more than strange as Yumoto was supposed to be already inside. He had immediately begun to imagine the worst scenarios, wondering in what state the room would be, before opening the door.
What he had found was a completely calm Yumoto, sitting next to En who had been reading. Atsushi had needed a few seconds to understand the situation. Unfortunately Yumoto had noticed him right away and had begun to talk endlessly.
He had never told Io and Ryuu but he knew that these two had noticed too.
And it had not been a one-time thing. In the club room, in the cafeteria, in the bath... As soon as En was beside him, Yumoto calmed down right away.
Atsushi had obviously told his best friend one day, who had no particular reaction... Except trying to get closer to the youngest to check by himself.
No one could have predicted that a month later, Atsushi would find En and Yumoto kissing furiously in the middle of the club room.
At that exact moment, he feared for his life. Because one day Gora would find out he had been the reason those two got together.
