Wait Wait Wait guys, come back, there's no Harem tag(yet), also the vibe she gives is like a Teacher
or a Nurse( ͡° ͜ʖ ͡°), but we should wait for the next chapter(s) to judge before reaching to a conclusion.
Also love the ''cracked'' look they have, wait... ''coming back to life'' with cracked parts hum........ reminds me of Dr. Stone.
(BTW I still stick even with a Harem :V).
