Feelings
After Lena and Lashara had joined the Nirvana Group, the two of the Lashara guard were relieved with their duty. Which was the main objective of Lashara, for joining their group. The group had something called strength equivalency.
Under which, those with no minimum test limit cannot join the group. Where the old man which had stopped their fight, register their strength level to be B+ class.
The topmost class in the first year, Lashara bodyguard's strength, did not match up to that level and ended up rejected.
What surprised Chen was Lena's strength, which was said to be above them, along with Lashara strength too. Looking at Chen's surprised expression, Lena felt quite happy.
To see him making those expressions, she had never seen before. Where Chen was allowed to have his own same room as Fatty Wall, at which Lena also joined the same room. Given she wanted to talk about their homeworld.
