When will the love constellation between light and night be unlocked?

We have to wait until level 30 to see it.

In this chapter, we can only see the ending of Charlie Su and Qi, so we need chapter 8 to unlock his scheme, which corresponds to the light, so we need to reach level 30 to see him, level 35 to attack thoroughly, and we need to choose the ending of the sun. Otherwise, we can't solve his ending.
