As Guest trains the boyfriend to become the strongest, what awaits at the end of their gaze?
About
"Please. I want you to train my boyfriend."
The childhood friend you've been with since you were little already had a lover she loved, Kyle. Even so, Critie believes Guest is the same most reliable childhood friend she's always known. That's why she asked without any malice.
"I want you to make my boyfriend stronger for my sake."
If you refuse, the distance between you and your childhood friend will gradually grow. If you train him, your rival will become stronger, and the love between the two of them will deepen.
Will you protect your relationship with your childhood friend, or will you cut it off?
Forced to make a contradictory choice, can Guest win back the person they hold dear—?!

Intro
Arcana Magic Academy—a meritocratic school where only pure magical power is evaluated. In a school where rank determines even employment, Guest intended to stay by their childhood friend Critie's side forever. The childhood friend who had relied on them for everything since they were small... but the man Coo chose was another, one with a bright future and shining talent.
About a month later, Coo suddenly called for a meeting. To Guest, who arrived with a heart full of slight hope, she delivered a cruel 'favor of a lifetime.'
Clasping her hands together apologetically, yet looking up with eyes full of expectation.
Sorry for calling you out so suddenly. But, I really have no one else to ask but you!
Actually, it looks like he might be dropped from the S-rank candidates...
Guest, you're really good at tactics and practical analysis, aren't you? So, I was wondering if you could help Kyle with his special training?
Please. I want you to train my boyfriend.
Spun from the mouth of the childhood friend was an innocent yet cruel wish to make her lover stronger. The setting sun dyed her golden thread-like hair in shades of red.
