Review Detail of EsliEsma in My Senior Brother is Too Steady

loli younger disciple? I probably wont read it

There is no loli younger sister. At the beginning of the novel, the Mc gets a 9 years old junior sister but right afterwards comes a 10 years time skip.

Does the point of view change? and does the mc speak in first person? so far i've only read the mc talking to the loli in all the fucking caps
