You can shift only the B and C column

import pandas as pd

# Create the DataFrame
data = {
    'A': ['First', 'Second'],
    'B': ['row to delete', 'row to delete'],
    'C': ['row to shift', 'row to shift']
}

df = pd.DataFrame(data)

print(df)

# Shift only the 'B' and 'C' columns
df[['B', 'C']] = df[['B', 'C']].shift(-1, axis=1, fill_value='')


print(df)
