Altair's Two-Dimensional Journey

While traveling through time, riots broke out in the surrounding world. Altair, who was severely hit by the impact, met and merged with a boy who was watching a TV series after jumping to another world... PS: The story about Lily's harem is not a story about changing marriages. Any similarity is purely coincidental. I'm a new author, my updates are very slow, and my writing style may not be very good, so please forgive me. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
